The following table list the defects corrected in this release of Subsystem Device Driver. See the Defects Details section for more information, if available, on a listed defect. Note: The following defect numbers are for IBM internal reference use only. ====================================================================== Defect # Description ====================================================================== 51788 In certain circumstances, the AIX HACMP system cannot identify the PVID of a Subsystem Device Driver physical volume when the "importvg" command is initialy executed. See Chapter 2 of Subsystem Device Driver Installation and User Guide for information about four (4) possible PVID scenarios for importing Subsystem Device Driver volume groups. 1163 The "datapath set adapter offline" command fails if any of the Subsystem Device Driver vpath devices is configured with a single path even though the path is not attached to this adapter. 1148 Add the Subsystem Device Driver default trace to display persistent reserve key. 1142 "cfallvpath" is added as a new Subsystem Device Driver configuration method. 1183 The new "cfallvpath" Subsystem Device Driver configuration method fails to check the maximum number of ESS LUNs supported by the Subsystem Device Driver. 1138 Script is changed to ensure that "extendvg4vp" checks for any opened logical volumes before calling "varyoffvg." 1135 Resolved the problem caused by path inaccessibility when unconfiguring the Subsystem Device Driver devices in the AIX HACMP environment. 1134 Turn on the 'f' flag when running the "mkvg4vp" command in the SMIT panel 1099 Support for "512" and "1024" block sizes in the SMIT panel: Under fastpath datapath_mkvg in the SMIT menu, "512" and "1024" are added to the selection list for "Physical partition size in megabytes" to match the settings in fastpath "mkvg." 1089, 1131 The new "savevg4vp" and "restvg4vp" commands are provided by the Subystem Device Driver to replace the "savevg" and "restvg" commands. 1087 Add a missing trace flag in the Subsystem Device Driver trace file. DEFECT DETAILS The following section provides additional information about the defects listed above (as applicable). ====================================================================== Defect #1142 "cfallvpath" as a new Subsystem Device Driver configuration method The "cfallvpath" command is added to achieve the following: 1. Greatly reduce the amount of time to configure the Subsystem Device Driver with a large number of ESS hdisks or to boot up the system configured with a large number of ESS hdisks and Subsystem Device Driver devices. 2. Avoid the potential failure to configure the Subsystem Device Driver due to the memory leak caused by AIX system calls. Use the "cfallvpath" command, instead of the "cfgmgr -1 dpo" command, to configure the Subsystem Device Driver devices with a large number of ESS hdisks. The "cfallvpath" command does not require any parameters. ====================================================================== Defect #1089 New "savevg4vp" and "restvg4vp" commands 1131 The "savevg4vp" (derived from savevg) command is designed to save an entire volume group created by the Subsystem Device Driver devices. It allows the device pvids to remain with the Subsystem Device Driver devices. You must replace the "savevg" command with the "savevg4vp" command in your script file to back up all files that belong to a specific Subsystem Device Driver volume group. Caution: Using the "savevg4vp" command to back up data will overwrite the data previously stored on the selected output medium. Data integrity of the archive might be comprised if a file is modified during the system backup process. Keep the number of system activities at a minimum during the system backup procedure. The "restvg4vp" (derived from restvg) command is designed to restore an entire volume group created by the Subsystem Device Driver. It allows the device pvids to remain with the Subsystem Device Driver devices. You must replace the "restvg" command with the "restvg4vp" command in your script file to restore all files that belong to a specific Subsystem Device Driver volume group. See Subsystem Device Driver Installation and User Guide for more information about using the "savevg4vp" and "restvg4vp" commands. 8.0 UTILITIES FOR IBM SUBSYSTEM DEVICE DRIVER ON AN ESS: ESS / DPO Custom Utilities for AIX. lsvp is a utility program that displays the Subsystem Device Driver vpath status from an ESS physical code perspective. You can use the lsvp program to set the Subsystem Device Driver vpath paths offline using an ESS location code. The lsvp program is available from the ibmpfe.essutil.rte file set (install package) for an AIX host system. You can obtain the ibmpfe.essutil.rte install package from the the following web site: http://www.ibm.com/storage/support/techsup/swtechsup.nsf/support/sddlink Tip: On the website, click on "Utilities for IBM Subsystem Device Driver / Data Path Optimizer on an ESS:" The following files are included in the ibmpfe.essutil.rte fileset: /usr/lpp/ibmpfe.essutil/README /usr/lib/methods/scsimap /usr/lib/methods/fcmap /usr/bin/lsess /usr/bin/ls2105 /usr/bin/lssdd /usr/bin/lsvp /usr/bin/get_ess_port /usr/bin/get_ess_vpd /usr/bin/get_ess_cudv Complete the following steps to install the ibmpfe.essutil.rte fileset: 1. Use smitty to install ibmpfe.essutil.rte file set 2. Choose the next set of options according to your needs. Note: - For SCSI device support: Use smitty to install ibmpfe.essutil.scsi.data fileset. - For FC device support: Use smitty to install ibmpfe.essutil.fibre.data fileset. Attention: You can install both the SCSI and FC support. However, to avoid the error messages described below, you should only install the support for the device types you have configured. You can run the following four programs from the command line: 1) lsvp 2) lsess 3) ls2105 4) lssdd Header definitions for all programs are as follows: Disk - hdisk name assigned by the host Location - physical location code of host adapter lun is accessed through LUN SN - unique serial number for each lun within the ESS Type - device and model Size - configured capacity of lun in giga bytes LSS - logical subsystem where lun resides Vol - volume number within the LSS Rank - unique identifier for each raid-array with the ESS C/A - cluster and adapter accessing the array S - shared by two or more ESS ports, Yes or No Connection - physical location code of ESS adapter lun is accessed through lsvp program descriptions and example: The lsvp shows the Subsystem Device Driver vpath status from an ESS physical location code perspective. Included is the capability to set the Subsystem Device Driver vpath paths offline using an ESS location code. Usage: lsvp [-adt] [-o] [-l location_code] -a Display SDD logical path to ESS physical location code -d Display path status for each vpath device -t Test physical access to hdisks, can only be used with -d option -o Attempts to set all SDD paths ONLINE -l Set SDD paths OFFLINE for specified ESS location code location_code must be in one of the following formats: single port = R1-Bx-Hy-Zz all ports on card = R1-Bx-Hy all ports on bay = R1-Bx Type the following at the command prompt: # lsvp -d The output should look similar to this: BAY-1(B1) BAY-2(B2) BAY-3(B3) BAY-4(B4) H1 H2 H3 H4 H1 H2 H3 H4 H1 H2 H3 H4 H1 H2 H3 H4 A B A B A B A B A B A B A B A B A B A B A B A B A B A B A B A B 0 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 1 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 2 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 3 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 4 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 5 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 6 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 7 - - - - - - Y - - - - - - - Y - - - - - - - Y - - - - - - - Y - 8 - - - - - - O - - - - - - - O - - - - - - - O - - - - - - - O - 9 - - - - - - O - - - - - - - O - - - - - - - O - - - - - - - O - 10 - - - - - - O - - - - - - - O - - - - - - - O - - - - - - - O - 11 - - - - - - O - - - - - - - O - - - - - - - O - - - - - - - O - Y = online/open O = online/closed N = offline X = not-available - = path not configured ? = path information not available PD = path down lsess program descriptions and example: The lsess program displays data collected from the fcmap and scsimap program invoked by cfgmgr. fcmap and scsimap issues scsi commands directly to the disks (inquiry,read capacity, and log sense) to collect the information displayed. Note: To run lsess, you will need to either restart your host system or run cfgmgr (AIX command to configure disks) with all 2105 vg's offline. This is only necessary for the initial run. Type the following at the command prompt: # lsess The output should look similar to this: Disk Location LUN SN Type Size LSS Vol Rank C/A S Connection ------ ------------ -------- ------------ ------ ----- ----- ------ ---- --- ----------- hdisk1 10-68-01[FC] 008FC106 IBM 2105-E20 2.0 10 8 1001 01 Y R1-B2-H4-ZA ls2105 and lssdd descriptions and examples: The ls2105 and lssdd programs format data collected by AIX and stored in the ODM when the disks were configured to the host. Type the following at the command prompt: # ls2105 The output should look similar to this: Hostname VG hdisk Location LUN SN S Connection Size LSS Vol Rank -------- -- ----- -------- ------ - ---------- ---- --- --- ---- hashark1 None hdisk1 10-68-01 008FC106 Y R1-B2-H4-ZA 2.0 10 8 1001 Type the following at the command prompt: # lssdd The output should look similar to this: Hostname VG vpath hdisk Location LUN SN S Connection Size LSS Vol Rank -------- -- ----- ----- -------- ------ - ---------- ---- --- --- ---- hashark1 sharkvg vpath0 hdisk1 10-68-01 008FC106 Y R1-B2-H4-ZA 2.0 10 8 1001 hashark1 sharkvg vpath0 hdisk9 10-68-01 008FC106 Y R1-B1-H4-ZA 2.0 10 8 1001 Note: ls2105, lssdd, and lsvp do not require a system restart or vg's to be offline for initial run. However, they do require the ibm2105.rte package to be at 32.6.100.3 code level (or higher). If lsess has not been run, the lssdd output will not contain LSS, Volume, and Rank information. Attention: If you are getting one of the following errors when running cfgmgr, it is because your 2105 devices are either all native SCSI or all FC. Method error (/usr/lib/methods/scsimap >> /var/adm/essmap.out): 0514-023 The specified device does not exist in the customized device configuration database. Method error (/usr/lib/methods/fcmap >> /var/adm/essmap.out): 0514-023 The specified device does not exist in the customized device configuration database. If you no not intend to have a mix of 2105-SCSI and 2105-FC, then you can eliminate the error by performing either: Use smitty to remove ibmpfe.essutil.fibre.data fileset (do this for all 2105-SCSI configurations) Use smitty to remove ibmpfe.essutil.scsi.data fileset (do this for all 2105-FC configurations) Note: Both actions will remove support for the device types you do not have configured. 9.0 NOTICES This information was developed for products and services offered in the U.S.A.
