This README file contains the most recent information about the IBM Subsystem Device Driver, Version 1 Release 5 Modification 1 Level 3 (SDD 1.5.1.3) for AIX. You should consult the SDD User's Guide to determine if the functionality described here applies to your product environment. See item 2 below. IBM recommends that you go to this Web site to get the most current information about this release of SDD: http://www.ibm.com/servers/storage/support/software/sdd.html You should carefully review the following information available through that site: 1. The most current README file. This will contain corrections to the readme file, corrections to the SDD User's Guide, and documentation updates made discovered since this copy of the README was prepared. 2. The SDD Users' Guide. Because SDD can be installed in so many different environments / configurations, detailed information about each environment is placed in the appropriate chapter of the SDD Users Guide. The 'Summary of Changes' section of the SDD Users' Guide can help you quickly determine if the latest changes affect you. 3. The Flashes. As we become aware of any information that is likely to impact a broad set of our customers, Flashes are prepared and posted on this site. You should review this section periodically to see any new Flashes that have been posted since your last review. For prerequisites information, be sure to look in the SDD User's Guide as well as the prerequisites section of this readme file for the latest updates. 1.1 Who should read this README file This README file is intended for storage administrators, system programmers, and performance and capacity analysts. The information in this file only applies to customers who run: 1. ESS or SVC or SVCCISCO 2. ESS and SVC 3. ESS and SVCCISCO 1.2 How to get help Go to the following Web site for SDD technical support and for the most current SDD documentation and support information: http://www.ibm.com/servers/storage/support/software/sdd.html Go to the following Web site for the IBM ESS Open Systems support: http://www.storage.ibm.com/hardsoft/products/ess/supserver.htm Go to the following Web site for IBM TotalStorage SAN Volume Controller support: http://www.ibm.com/servers/storage/support/virtual/2145.html Go to the following Web site for IBM TotalStorage SAN Volume Controller for Cisco MDS 9000 support: http://www.ibm.com/servers/storage/support/virtual/2062-2300.html Call one of the following numbers to obtain nontechnical or administrative support, such as hardware and software orders, hardware maintenance, services contract of entitlement, and invoices: .For commercial or state and local support operations: 1-877-426-6006 (Listen to the voice prompts) .For business partner support operations: 1-800-426-9990 .For federal government support operations: 1-800-333-6705 --------------------------------------------------------------------------------- 2.0 Prerequisites for SDD Prior to installing SDD, you should install the latest version of AIX host attachment script. For ESS devices: Install ibm2105.rte. The latest version is 32.6.100.21. Attention: Starting from ibm2105.rte version 32.6.100.21, ESS FC devices will be configured as "IBM FC 2105", as seen from the "lsdev -Cc disk" output. This is changed from "IBM FC 2105XXX", where 'XXX' is the ESS device model, such as F20 or 800. There are two side effects of this change: a) To avoid ODM corruption, you will need to remove all ESS FC hdisks and all SDD vpath devices from your host system if you are upgrading from ibm2105.rte version 32.6.100.19 or ealier to ibm2105.rte version 32.6.100.21 or later. b) HACMP processing will fail to bring up volume groups in concurrent mode. In order to work around this issue, the /etc/cluster/conraid.dat HACMP file must be updated to include the following line: 2105*** If the /etc/cluster/conraid.dat HACMP file does not exist, it should be created and contain this line. For SVC devices: Install devices.fcp.disk.ibm2145.rte. The latest version is 1.1.0.3. For SVCCISCO devices: Install devices.fcp.disk.ibm2062.rte. The latest version is 1.1.0.0. ================================================================================= 2.1 Procedure for upgrading AIX OS, Host attachment, and/or SDD The following procedure should be used when you want to upgrade: - AIX OS only* - Host attachment + AIX OS* - SDD + AIX OS - Host attachment + SDD - Host attachment only - SDD + Host attachment + AIX OS * Upgrading the AIX OS will always require you to install the SDD which corresponds to the new AIX OS level. In the case where you want to upgrade SDD only, follow the procedure in the SDD User's Guide. 1. Have rootvg on local scsi disks. 2. Stop application running on SDD Volume Groups/File Systems. 3. Umount all File Systems of SDD volume group, vary off all SDD volume groups. 4. If upgrading OS, save output of lspv command to remember pvids of VGs. 5. If upgrading OS, export volume groups with exportvg. 6. Remove SDD vpath devices with rmdev command. 7. Remove 2105 hdisk devices with rmdev command. 8. If upgrading OS, run 'stopsrc -s sddsrv' to stop sddsrv daemon. 9. If upgrading OS, deinstall SDD. 10. If required, upgrade ibm2105.rte. The recommended version is 32.6.100.18 if you do not need support for ESS model 750. For ESS model 750 support, you will need version 32.6.100.21. 11. If upgrading OS, migrate AIX OS level. 12. If OS upgraded, boot to new AIX level with no disk groups online except rootvg, which is on local scsi disks. Reboot will automatically start at the end of OS upgrade. 13. If OS upgraded, install SDD for the new OS level. Otherwise, if required, upgrade SDD. 14. If OS not upgraded, configure hdisks with the 'cfgmgr -vl fcsX' command. 15. Configure SDD vpath devices by running 'cfallvpath'. 16. If OS upgraded, use lspv command to find out one physical volume which has a pvid matching the previous SDD VG's pv. Example: ================================================================================ Previous lspv output (from step 4): hdisk0 000bc67da3945d3c None hdisk1 000bc67d531c699f rootvg active hdisk2 none None hdisk3 none None hdisk4 none None hdisk5 none None hdisk6 none None hdisk7 none None hdisk8 none None hdisk9 none None hdisk10 none None hdisk11 none None hdisk12 none None hdisk13 none None hdisk14 none None hdisk15 none None hdisk16 none None hdisk17 none None hdisk18 none None hdisk19 none None hdisk20 none None hdisk21 none None vpath0 000bc67d318fb8ea SDDVG0 vpath1 000bc67d318fde50 SDDVG1 vpath2 000bc67d318ffbb0 SDDVG2 vpath3 000bc67d319018f3 SDDVG3 vpath4 000bc67d319035b2 SDDVG4 Current lspv output (from this step): hdisk0 000bc67da3945d3c None hdisk1 000bc67d531c699f rootvg active hdisk2 000bc67d318fb8ea None hdisk3 000bc67d318fde50 None hdisk4 000bc67d318ffbb0 None hdisk5 000bc67d319018f3 None hdisk6 000bc67d319035b2 None hdisk7 000bc67d318fb8ea None hdisk8 000bc67d318fde50 None hdisk9 000bc67d318ffbb0 None hdisk10 000bc67d319018f3 None hdisk11 000bc67d319035b2 None hdisk12 000bc67d318fb8ea None hdisk13 000bc67d318fde50 None hdisk14 000bc67d318ffbb0 None hdisk15 000bc67d319018f3 None hdisk16 000bc67d319035b2 None hdisk17 000bc67d318fb8ea None hdisk18 000bc67d318fde50 None hdisk19 000bc67d318ffbb0 None hdisk20 000bc67d319018f3 None hdisk21 000bc67d319035b2 None vpath0 none None vpath1 none None vpath2 none None vpath3 none None vpath4 none None In this case, hdisk2, hdisk7, hdisk12, and hdisk17 from the current lspv output has the pvid which matches the pvid of SDDVG0 from the previous lspv output. So, use either hdisk2, hdisk7, hdisk12, or hdisk17 to import the volume group with the name SDDVG0. ================================================================================ 17. Run hd2vp on all SDD volume groups. 18. Vary on all SDD volume groups. 19. Mount all file system back. --------------------------------------------------------------------------------- 3.0 SDD Change History ================================================================================= 3.1 Defects Fixed 3.1.1 Common 2613 Dynamic enable/disable queue depth may not enable/disable queue depth for all vpaths. On host systems running heavy I/O, this exposes a SDD problem in which queued I/O could be lost, causing the application that's sending the I/O to hang. 2601 Disable following two datapath commands, in order to support AIX parallel device configuration: datapath set adapter N suspend datapath set adapter N resume The above commands were disabled for two reasons: 1) Starting with SDD host attachment script ibm2105.rte version 32.6.100.21, ESS devices have a new cfgmgr_psafe PdAt attribute. This attribute is designed to support AIX parallel disk configuration methods. Each time an hdisk is reconfigured with this feature, the device minor number may change. This could cause an AIX system crash when suspending and resuming an adapter during an AIX HBA hot-plug. 2) With multiple subsystems attached to one host, reconfiguration of hdisks may cause hdisks to be configured in a different order from the previous configuration. This could also cause an AIX system crash when suspending and resuming an adapter during an AIX HBA hot-plug. 2597 Add savebase call when change SDD device/path ODM attributes on fly so that after a system reboot, the ODM attribute values will not go back to the default 2578 An AIX dump failure problem may occur during system crashes or user invoked forced dump if an AIX system has a large number of ESS/SVC/SVCCISCO devices configured 2577 SDD vpath device open failures may occur if a user application issues an openx with 'ext' flag of SC_FORCED_OPEN or SC_FORCED_OPEN_LUN to vpath devices 2463 Return error for operations on volume group with missing/no pv 2459/2464 (DCR MR012204217) Reduce issuing SCIOLQWWN cmd from sddsrv to fabric 2451 Remove recalculation when querying adapter infomation 2312/2484/2502 (cmvchvtl def 59562) Enhance SDD first time data capture 2425 (cmvchvt1 def 60371) Inconsistent registration key may be generated on AIX 4.3 2414 sddsrv needs to free odm list to prevent running out of memory 2411 Removing a vpath device while running 'datapath query device' may hang the command 2367 Change file permissions of shipped files to improve security 2364 Change the format of 'lquerypr -Vh /dev/hdisk#' to eliminate redundant registration key information 2363 Improve efficiency of dynamic qdepth 2355/2456 (mc def 95980) System crash with corrupted vpath_dmpxbuf; Remove extra load count of the driver 2343/2346 (cmvchvt1 def 58218) Allow disabling sddsrv tcpip port; Always write output of SDDSrv trace to a file to prevent loss of trace data 2313 (mc def 93894) Change the order of hd2vp and varyonvg during migration restoration process to improve performance 2252 If subsystem supports persistent reserve, all added paths will always be opened 3.1.2 ESS defects 2351 Compare only 8 digits of serial number for ESS LUNS during addpaths 2288 (mc def 93859) Input data in command buffer was not copied into kernel buffer and thus caused fc_essfmt to fail 3.1.3 SVC defects NONE 3.1.4 SVCCISCO defects NONE ================================================================================= 3.2 New Features 2390 (PCR 2603) Support for ESS model 750 Starting from SDD v1.5.1.110, ESS model 750 can be configured as SDD vpath devices. As with other vpath devices, users will be able to configure, do I/O, failover/failback, and do CCL on ESS model 750 devices. 2321/2394 (PCR 2531) Fiber and SCSI support for 'essutil' in datapath program 2314 Dynamically enabling/disabling the queue depth logic in datapath program 2296 Increase the size of SDD trace file to 256k 2281 (PCR 2426) Dynamic Remove Path and Adapter This feature allows users dynamically to remove certain paths or 'hot swap' (or replace) a PCI adapter on newer pSeries machines. Removal of any paths and/or adapters does not interrupt current I/O and SDD automatically reconfigures itself. Supported AIX Operating System levels are AIX v4.3, v5.1, and v5.2 Note: PCI Hot Plug only supports on AIX 5L and up. ================================================================================= 3.3 Feature Details NONE ================================================================================= 3.4 Known Issues NONE ================================================================================= 3.5 Correction to User's Guide Page 29 of the SDD User's Guide has an incorrect statement. Under section "Controlling I/O flow to SDD devices with the SDD qdepth_enable attribute", the fourth paragraph should have been deleted: "To disable queue depth logic, you should change the qdepth_enable attribute setting in ODM by executing chdev." --------------------------------------------------------------------------------- 4.0 User license agreement for IBM device drivers NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.
