Installing the operating system to SSA disks only from OS/2 media ----------------------------------------------------------------- If you are installing your operating system onto an SSA disk then follow the instructions in your SSA Installation and Users Guide to: - Boot from the DOS Configurator and Service Aids diskette in order to attach an SSA resource to your PC Server. Before installing the OS/2 operating system, it is suggested that the SSA device drivers be copied onto the second of the OS/2 installation diskettes. You can install OS/2 without doing these modifications but the installation process can be much slower. The process of modifying the second installation diskette is as follows: 1) Edit the config.sys and add the statements: BASEDEV-ISSAPCI.ADD BASEDEV-ISSADSK.ADD just before the first BASEDEV- statement in the config.sys file. This causes the SSA device drivers to load first. 2) Copy ISSAPCI.ADD and ISSADSK.ADD from the OS/2 Device Driver and Utilities diskette onto the installation diskette. You will need approximately 196000 bytes of free space and depending on your system configuration you may be able to delete some of the following files in order to provide room for the SSA device drivers. IBM2FLPY.ADD Supports disk drives on Microchannel computers. IBM2ADSK.ADD Supports non-SCSI hard drives on Microchannel systems. IBM2SCSI.ADD Supports SCSI hard drives on Microchannel system. Note: The three device drivers listed above can only be deleted from an installation diskette associated with a EISA/PCI PC Server. The MCA/PCI PC Server (e.g. PC Server 720) requires all of the above. PRINT02.SYS Supports local printers on Microchannel systems. IBMIDECD.FLT IDE connected CD. Also, depending on other vendor options which may be installed, SONY*.* TOSH*.* HIT*.* NEC*.* CHI*.* AHA152*.* AHA154*.* SBCD2.* LMS206.* Now follow the installation instructions which you will have received with your operating system. IMPORTANT NOTE -------------- The ISSAPCI.ADD and the ISSADSK.ADD devices drivers may be copied to the root (\) directory during the install process. These two files should be moved (i.e. copied and deleted) to the \OS2 directory once installation of the Operating System has completed. Installing the operating system to SSA disks only from SERVER GUIDE ------------------------------------------------------------------- IBM Operating System/2 (OS/2) WARP Server SMP ------------------------------------------------ If you are installing your operating system onto an SSA disk then follow the instructions in your SSA Installation and Users Guide to: - Boot from the DOS Configurator and Service Aids diskette in order to attach an SSA resource to your PC Server. NOTE: Attach ONLY the devices which are to be the target for the installation. During installation the system reboots several times. At the the reboot which gives the error message: OS2KRNL is not valid It is necessary to copy the version of OS2KRNL present in the root directory of the D drive to the root directory of the C drive. In order to do this, the attributes must be changed. Reboot the machine from a DOS diskette with ATTRIB.EXE available on it and with the following command line: attrib -h -r -s C:\OS2KRNL [ENTER] Change the attributes. The OS2KRNL file can now be copied: copy D:\OS2KRNL C:\OS2KRNL [ENTER] And the attributes reapplied: attrib +h +r +s C:\OS2KRNL [ENTER] Rebooting the machine with the diskette removed will allow the installation to complete normally. IBM Operating System/2 (OS/2) WARP Server -------------------------------------------- If you are installing your operating system onto an SSA disk then follow the instructions in your SSA Installation and Users Guide to: - Boot from the DOS Configurator and Service Aids diskette in order to attach an SSA resource to your PC Server. NOTE: Attach ONLY the devices which are to be the target for the installation. During the installation the message "LOADING SYSTEM FILES PLEASE WAIT" is displayed. At this point the machine and disk activity stop. When this happens reboot the machine from a bootable DOS diskette which has a text editor available on it. Edit the OS2INST.RSP file on the D drive and insert above the line: ConfigSysLine-BASEDEV The two lines: ConfigSysLine-BASEDEV-ISSAPCI.ADD ConfigSysLine-BASEDEV-ISSADSK.ADD Copy the IBM SSA Device drivers from the driver diskette into the OS2 directory on C. copy A:\ISSAPCI.ADD C:\OS2 [ENTER] copy A:\ISSADSK.ADD C:\OS2 [ENTER] Rebooting the machine with the diskette removed will allow the installation to complete normally. Installing IBM SSA RAID Adapter Device Driver and Utilities for OS/2 -------------------------------------------------------------------- The software required to support the IBM SSA RAID Adapter for your OS/2 operating system can be simply installed by inserting the SSA RAID Adapter, OS/2 Device Drivers and Utilities, diskette into your diskette drive, typing the command: a:install [ENTER] The install program will copy the device drivers to the appropriate directory and modify your system's CONFIG.SYS file to ensure that these device drivers will be correctly started at the next, and subsequent, system initialisation time. The install program will also copy the utility software into a directory (default of c:\issa) and will create an IBM SSA RAID folder on your desktop, within which you will find the three utility programs of: SSA Configurator SSA Event Logger SSA Topology Display A shadow of the SSA Event Logger will also be placed in the system's startup folder so that it will automatically be invoked whenever your system is initialised. NOTE: The Install program automatically updates your config.sys file. In the unlikely event that you have manually amended the entry for "basedev-issapci" or "basedev-issadsk" it is possible that a duplicate entry will be made. Such duplicate entries can cause the operating system to hang and if you have amended the original lines please ensure that the config.sys file created as a result of the installation process only contains one reference to the IBM SSA RAID Adapter device drivers. On early (beta) releases of the device drivers, the device drivers were named "IPNDD.ADD" and "PCIKNL.ADD". Please ensure that all reference to these names are deleted from the config.sys file. Manual Install -------------- If the Install Program does not work on your system, or it is necessary to manipulate the files manually, then the following notes will be of use. The files on the diskette are in a packed format, and the EPFIUPK2.EXE program can be used to unpack them. The EPFIUPK2 program will create the correct file names. To copy the files manually (replicate the action of the install program), follow the steps provided below: 1) Create a directory in which to store the IBM SSA Adapter software. If 'ISSA' were to be used, then type: mkdir ISSA [ENTER] 2) Copy this file onto the new directory by issuing the commands: copy a:readme.txt \issa\readme.txt [ENTER] 3) Now unpack the SSA device drivers and utility software by issuing the commands: cd ISSA [Enter] copy a:*.ex_ . [Enter] copy a:*.nl_ . [Enter] copy a:*.ic_ . [Enter] copy a:*.tx_ . [Enter] copy a:epfiupk2.exe . [Enter] epfiupk2 issacfg.ex_ [Enter] epfiupk2 issaelog.ex_ [Enter] epfiupk2 issatopo.ex_ [Enter] epfiupk2 cfgmenu.nl_ [Enter] epfiupk2 cfghelp.nl_ [Enter] epfiupk2 evnlog.nl_ [Enter] epfiupk2 evncntlf.tx_ [Enter] del *.ex_ [Enter] del *.nl_ [Enter] del *.tx_ [Enter] del epfiupk2.exe [Enter] 4) Copy the device drivers to the \OS2 directory by issuing the commands: copy a:ISSAPCI.ADD \OS2 [Enter] copy a:ISSADSK.ADD \OS2 [Enter] 5) Edit the CONFIG.SYS file and, at the bottom of the file, add the lines: BASEDEV-ISSAPCI.ADD BASEDEV-ISSADSK.ADD NOTE: If you have previously installed an older version of the IBM SSA RAID Adapter card, the device drivers may have been named "PCIKNL.ADD" and "IPNDD.ADD". Please delete any reference to these from the CONFIG.SYS file. 6) Now create a method of accessing the SSA utility software. One method is to create program objects within a new folder. The steps required to do this are outlined below: a) Drag a Folder object from the OS/2 System Templates folder onto your desktop. Open the settings for this new folder and in "General" change the folder name to IBM SSA RAID, and you can find an SSA icon by searching on the \ISSA path. b) Drag a Program object from the OS/2 System Templates folder put this into the new (SSA) Folder. A "Program Settings" prompt will be provided. The Path and file name: should be entered as: c:\ISSA\issacfg.exe (where c: and \ISSA must match the drive and directory in which you have expanded the SSA software) No Parameters are required but the Working directory should be entered as: C:\ISSA Under the General section, change the Title: to read SSA Configurator and, if required, choose the SSA icon by finding the ICON on the SSA path. c) Drag a Program object from the OS/2 System Templates folder put this into the new (SSA) Folder. A "Program Settings" prompt will be provided. The Path and file name should be entered as: c:\ISSA\issatopo.exe (where c: and \ISSA must match the drive and directory in which you have expanded the SSA software) A single parameter is required - this is the PCI slot number in which the SSA adapter has been placed. The Working directory should be entered as: C:\ISSA Under the General section, change the Title: to read SSA Topology and, if required, choose the SSA icon by Finding the ICON on the SSA path. d) Drag a Program object from the OS/2 System Templates folder put this into the new (SSA) Folder. A "Program Settings" prompt will be provided. The Path and file name: should be entered as: c:\ISSA\issaelog.exe (where c: and \ISSA must match the drive and directory in which you have expanded the SSA software) No Parameters are required but the Working directory should be entered as: C:\ISSA Under the General section, change the Title: to read SSA Event Logger and, if required, choose the SSA icon by Finding the ICON on the SSA path. 7) Now create a shadow of the SSA Event Logger in the startup folder, such that the Event Logger will be started each time your system is initialised. To do this, open the startup folder (usually found within the OS/2 System folder and drag a copy (Ctrl+Right Hand Mouse Button) of the SSA Event Logger object from the IBM SSA RAID folder to the Startup Folder. For information, the following files will have been expanded. SSA Device Drivers ISSAPCI.ADD ISSADSK.ADD Support software ISSACFG.EXE -- The configuration tool CFGMENU.NLS - ) CFGHELP.NLS - ) National Language Support (UK English) ISSAELOG.EXE -- The SSA Event Logger, with pop-up menu for error notification EVNCNTLF.TXT - SSA Event Logger control file EVNLOG.NLS - National Language Support (UK English) ISSATOPO.EXE -- SSA Topology Generation Setting up the Topology Display Program --------------------------------------- The topology display program uses the "Node Number" assigned by the SSA Device Driver software to identify which SSA Adapter's resources are to be displayed. You could create a different Topology Display object for each adapter installed in your system. The easiest way to determine the node number(s) is to run the SSA Configurator program and, from the SSA Adapter menu make note of the node number(s) assigned to each adapter. Alter the settings for the ISSATOPO program and set the PARAMETERS value to a single node number obtained above. If you have more than one adapter installed then create other program objects in the IBM SSA RAID folder and, for each adapter installed, set the PARAMETERS value to an alternative node number. NOTE: For convenience of use, you may also like to alter the name of the program object to indicate which adapter's SSA topology is being displayed. Using SSA for Operating System Boot ----------------------------------- If your primary boot device is a logical SSA drive, then the SSA adapter must be installed into a PCI slot with a lower number than that in which any SCSI adapters are installed. You should also edit the config.sys file to ensure that the SSA device drivers (ISSAPCI.ADD and ISSADSK.ADD) are loaded before any SCSI device drivers. Reported problems and/or workarounds ------------------------------------ 1) Isolated instances have been seen when a 520 server, will not boot first time from an operating system installed on an SSA DRIVE. The temporary solution is to reboot the PC Server. 2) It has been observed that, if a fixed disk drive fails (or an array goes offline, due to the failure of more than 1 member), OS/2 can "hang". Under normal circumstances an error message such as "The x: drive is not ready" will be generated by the Operating System. The rarer "hang" condition is not related to whether or not your SSA RAID Adapter is installed - it appears to be related to the Operating Systems inability, in some circumstances, to continue in the event of one of its fixed drives failing due to a hardware fault. 3) If you wish to create a RAID array you should ensure that all of the disks you elect to use as array members are the same capacity. NOTE: The smallest capacity of an array member is used when determining the size of the array. Adapter Firmware Download - ISSAADLD.EXE ------------------------- What it does ------------ ISSAADLD downloads an adapter microcode image to a specific SSA adapter, or to all SSA adapters it can find. Usage ----- usage: issaadld [-n node] [-a] [-Q] microcode flags: -n node identify adapter by node number (default all adapters) -a microcode is in AIF format (default is customer package) -Q quiet mode (default is verbose) microcode input adapter microcode image file Examples -------- To download a particular adapter microcode image (LD960701.dnd, for instance) to all SSA adapters: issaadld LD960701.dnd To download just to the adapter which is 'Node 13':- issaadld -n 13 LD960701.dnd *** IMPORTANT *** ----------------- Do NOT download whilst disks are performing I/O. All open occurrences of the SSA Configurator should also be closed, prior to performing the download. Only use this utility program when instructed to do so by your service representative since downloading incorrect images, for example, could have a detrimental effect on your SSA Subsystem. DASD Microcode Download - ISSADDLD.EXE -------------------------------------- ISSADDLD downloads a disk microcode image to a specific disk, or to all disks on a given SSA Adapter, or to all disks on all SSA Adapters. usage: issaddld [-a node] [-u uid] [-v vendor] [-f] [-q] microcode flags: -a node identify adapter by node number (default all adapters) -u serial 15 character full serial number (default all disks) -v vendor identify drive vendor (default is IBM) -f force download (default is to upgrade) -q quiet mode (default is verbose) microcode input disk microcode image file Examples -------- To download a new IBM DFHC microcode image (for instance, DFHC7968.DL) to all the disks on all the adapters issaddld DFHC7968.DL To update all the DFHC disks on the adapter referred to as node 13:- issaddld -a 13 DFHC7968.DL Important --------- Do not download to disks whilst they are performing I/O. Only use this utility program when instructed to do so by your service representative since downloading incorrect images, for example, could have a detrimental effect on your SSA Subsystem. Errors may be generated in SSA Event Log. These can be ignored and are a result of adapter reset which is necessary to initialise the new microcode. SSA Configurator Error Messages ------------------------------- The Configurator does not currently display all error codes it in a meaningful textual fashion. The error codes include: 0xfffd : General non-specific failure return code. 0xfffc : Hardware error. 0xfff8 : Illegal request. 0xfff0 : Not in table. Can't find disk with given serial number. 0xffe2 : Not yet implemented. 0xffef : Disk is currently offline. 0xffe0 : Not found. 0xfe1e : Array is broken or degraded. Some operations require a non-degraded array. 0xfe1a : NVRAM error. Its probably full with dormant entries. You could go and delete a few and then retry. 0xfe17 : Bad component exchange candidate. 0xfe18 : Array is broken. Some operations require a non-broken array. 0xfe13 : Bad new component serial number. New component is not suitable for component exchange. 0xfe11 : Bad disk serial number. Perhaps the disk went offline. 0xfe0c : Bad serial number. Perhaps there is already an array with this name. 0xff3a : Can't delete in-use resource. You can only delete dormant NVRAM entries. 0xff39 : Operation is not applicable for resource type. Perhaps you're trying to do a disk type of operation to an NVRAM entry (you can only list and delete these). 0xff38 : NVRAM is defective. The only sensible option here is to replace the module.
