The SDD driver and SDDPCM module can not coexist on one server. You must install the following host attachment for SDDPCM to support DS4000 and 5000 storage devices: ESS/DS8000/DS6000/SVC/DS4000/DS5000: devices.fcp.disk.ibm.mpio.rte (version 1.0.0.15) Following lists of required AIX and VIOS apars and service packs are cumulative. Apars required in earlier versions of SDDPCM packages are also required for later versions of SDDPCM packages, unless specifically noted as 'no longer applicable' or 'not required'. Note: VIOS is not supported with SDDPCM on DS4000 and DS5000 subsystem devices. ESS/DS8000/DS6000/SVC: If you are running SVC release which includes APAR IC55826 (SVC v4.2.1.6 and above), or SVC release prior to SVC v4.2.1.6 with an iFix on LONG BUSY support, the following AIX APARs are required for your AIX Technology Level: AIX52 TL10: APAR IZ08216 IZ20170 IZ28287 AIX53 TL06: APAR IZ06622 IZ20198 IZ28285 AIX53 TL07: APAR IZ06490 IZ19199 IZ26561 AIX53 TL08: APAR IZ07063 IZ20199 IZ26655 AIX53 TL09: APAR N/A, IZ20177, IZ30257 AIX61 TL00: APAR IZ09534 IZ20201 IZ26657 AIX61 TL01: APAR IZ06905 IZ20202 IZ26658 AIX61 TL02: APAR N/A, IZ20103, IZ29837 Note: N/A means this APAR is already included in the base Technology Level. The AIX APARs are available from AIX fix central website: http://www-912.ibm.com/eserver/support/fixes/fixcentral/main/pseries/aix If you are running SVC release which includes APAR IC55826 (SVC v4.2.1.6 and above), or SVC release prior to SVC v4.2.1.6 with an iFix on LONG BUSY support, and your system is configured as VIO server with VIOS level 1.5.2.1, the following VIOS interim fixes are required: VIOS Level 1.5.2.1 Interim Fix IZ19199 IZ26655 DS4000/DS5000: If you are running DS4000 or DS5000 storage subsystem, this version of SDDPCM package requires host system having at least AIX53 TL06 with all latest PTFs or AIX610 with all latest PTFs. Following AIX APARs are required for DS4000 or DS5000 subsystem devices: AIX53 TL06: APAR IZ36257 AIX53 TL07: APAR IZ36258 AIX53 TL08: APAR IZ36259 AIX53 TL09: APAR IZ36203 AIX53 TL10: APAR IZ36343 AIX53 TL11: APAR IZ36538 AIX61 TL00: APAR IZ36255 AIX61 TL01: APAR IZ36256 AIX61 TL02: APAR IZ36221 AIX61 TL03: APAR IZ37573 AIX61 TL04: APAR IZ37960 The AIX APARs are available from AIX fix central website: http://www-912.ibm.com/eserver/support/fixes/fixcentral/main/pseries/aix Attention: If your server is booting from SAN boot disk and you are migrating AIX OS and SDDPCM, refer to the instructions in SDD User's Guide and this flash: http://www-01.ibm.com/support/docview.wss?rs=540&context=ST52G7&uid=ssg1S1002845&loc=en_US&cs=utf-8&lang=en --------------------------------------------------------------------------- 3.0 SDDPCM change history =============================================================================== 3.1 Defects Fixed 4532 Inconsistent adapter state after rmpath/mkpath sequence 4533 I/O fail on DS4K/5K if only 2 passive paths are online while other paths are offline 4539 pcmsrv fails to recover FAILED paths after dynamic tracking event with certain dynamic tracking settings. 4541 pcmsrv hangs while stopping if tcpip port is enabled on AIX5.3 or older version 4547 pcmsrv on AIX5.2 hung in close function call 4542 pcmpath query device command doesn't display total number of device. 4544 essmap can't display LUN capacity correctly if LUN size > 2TB 4545 Need to display simple and clear error message if no device configured 4550 Cache hint disabled due to data structure mismatch 4554 For DS4K/5K devices, SDDPCM driver failed to reserve last path in OPEN state 4557 (PMR816119) Remove last device may cause system crash or displaying GEN_XMDB errlog 4561 DS4K/5K reset/ccdl error injection failed, caused by failover control logic =============================================================================== 3.2 New Features none =============================================================================== 3.3 Feature/defect Details none =============================================================================== 3.4 Known issues SDDPCM supports 'pcmpath set adapter online|offline aa|ap' command. For FC adapter connected to DS4000 or DS5000 active/passive storage devices, you should use 'ap' parameter to indicate this is an adapter connected to DS4000 and/or DS5000 storages devices. If an adapter is connected to other storage devices, then you should use 'aa' parameter. Since set an adapter OFFLINE may cause DS4000 and/or DS5000 LUN fails over to an alternate controller, this command is only supported when the AIX server has one DS4000 or DS5000 storage subsystem configured. This command may not work correctly if you have more than one DS4000 or DS5000 storage subsystem devices configured on one AIX server, and 'set adapter offline' command causes multiple subsystem device models migrating from one controller to alternate controller. Please refer to SDD User's Guide, chapter 3 for detail information of this command. There are known AIX disk driver configuration issues, which fails the migration of DS4000 and/or DS5000 subsystem devices from fcparray(RDAC) driver non mpio devices to SDDPCM mpio devices; or from AIX native mpio devices to SDDPCM mpio devices. Therefore, the SAN boot function is not supported with DS4000 and DS5000 subsystem devices at this release, until AIX disk driver configuration problem is resolved. VIOS is not supported with SDDPCM on DS4000 and DS5000 subsystem devices. If user issues 'pcmpath set device M path N offline' to set last active path offline, this will cause LUN to failover to an alternate controller, and swap its active and passive paths. There is a known issue that sometimes this command may also incorrectly cause other LUNs to failover to alternate controller and swap the active and passive paths. If user removes host FC HBA port from DS4000 or DS5000 storage subsystem while application is running, this will cause I/O performance degradation. The correct procedures are: 1. identify the host FC HBA you plan to remove from DS4000 or DS5000 storage subsystem 2. issue 'pcmpath set adapter X offline ap' or issue 'pcmpath set device M path N offline' command to set all the paths that connected to this FC HBA you plan to remove offline. 3. from the DS4000 or DS5000 storage subsystem to remove the FC HBA port. 4. if removing this host FC HBA port is permanent configuration change, make sure you remove this configuration on the host side by issuing either remove adapter or remove path command. =============================================================================== 3.5 Corrections to User's Guide On p. 102, the statement "HACMP and VIO are not supported with DS4000 and DS5000 storage subsystems." is incorrect. HACMP is now supported with DS4000 and DS5000 storage subsystems. This statement should read "VIO is not supported with DS4000 and DS5000 storage subsystems." On Page 127 the description of section "Starting the SDDPCM server manually" should be read as: If pcmsrv did not start automatically after you performed the SDDPCM Installation and configured supported storage devices, you can start pcmsrv by entering: startsrc -s pcmsrv -e "XPG_SUS_ENV=ON" On Page 127 the description of section "Stopping the SDDPCM server" should be read as: However, in certain cases when you want to permanently (not to start even after a system restart) disable pcmsrv, you must comment out the following line in the system init table (/etc/inittab): srv:2:wait:/usr/bin/startsrc -s pcmsrv -e "XPG_SUS_ENV=ON" > /dev/null 2>&1 On page 108 the description of #2 under "installing SDDPCM from CD-ROM" should be read as: 2. The AIX SDDPCM host attachment package (devices.fcp.disk.ibm.mpio.rte) should be installed along with SDDPCM package (devices.sddpcm.52.rte, devices.sddpcm.53.rte, or devices.sddpcm.61.rte). Note: Do not reboot the system if you only have SDDPCM host attachment package installed. On page 108, under "Installing and upgrading the AIX SDDPCM host attachment" A warning should be added: warning: Do not reboot the system if you only have SDDPCM host attachment package installed. On page 108, the last paragraph of "Installing and upgrading the AIX SDDPCM host attachment" section should be read as: For AIX SDDPCM host attachment installation and upgrade instruction from the CD, see the Host System Attachment Guide for your storage device. Do not reboot the system before SDDPCM package is installed on the system. For AIX SDDPCM host attachment installation and upgrade from the SDD download Web site, use following procedure: 1. Download code from the Web site that is appropriate for your system. 2. Move the downloaded file to the /usr/sys/inst.images directory. 3. Change directory to the /usr/sys/inst.images directory. 4. Untar the downloaded file: for example, tar -xvf devices.fcp.disk.ibm.mpio.rte.tar. 5. Update the .toc file. For example: pwd rm -i .toc inutoc . grep -i devices.fcp.disk.ibm .toc This command should reflect the newer SDDPCM host attachment version that will be uploaded. 6. From your desktop window, enter smitty install_update and press Enter to go directly to the installation panels. The install and Update Software menu is displayed. 7. Highlight Install Software and press Enter. 8. Enter . to indicate the current directory and press Enter. 9. Highlight Software to Install and press F4. The Software to install panel is displayed. 10. Select the devices.fcp.disk.ibm.mpio.rte package 11. Press Enter. The Install and Update from LATEST Available Software panel is displayed with the name of the software that you selected to install. 12. Check the default option settings to ensure that they are what you need. 13. Press Enter to install. SMIT responds with the following message: ARE YOU SURE?? Continuing may delete information you may want to keep. This is your last chance to stop before continuing. 14. Press Enter to continue. The installation process may take a few minutes to complete. 15. When the installation or upgrade is complete, press F10 to exit from SMIT. 16. If this is a host attachment installation, do not reboot the system until you have SDDPCM package installed; if this is host attachment upgrade, and SDDPCM package is already installed on the system, then reboot the system to complete the host attachment upgrade. User's Guide 1.8-2.4* version, on page 134, under "3. To query and display which type of persistent reservation is on a device, enter pcmquerypr -Vh /dev/hdisk#.", a note should be added: Note: Since SVC LUN returns Good status for SCSI-3 persistent reserve commands, even SCSI-2 reserve presents on the LUN, therefore, pcmquerypr command can not be used to verify if SCSI-2 reserve presents on the SVC LUN or not. --------------------------------------------------------------------------- 4.0 User license agreement for IBM device drivers NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.
