Symantec Enabled Arrays: Array Support Library and Array Policy Module for SUN ST6580/6780 Series Arrays in explicit ALUA mode on Veritas Volume Manager (tm) 5.0 RP5 and later for HP-UX 11iv3

Solution



This TechFile provides information on the Array Support Library (ASL) and Array Policy module (APM) for SUN ST6580/6780 Series Arrays in explicit ALUA mode on Veritas Volume Manager (tm) 5.0 RP5 and later for HP-UX 11iv3

For general information about ASLs, see TechNote 249446 (link in the Related Documents section of this TechFile)

ASL Package Name: VRTSLSIALUAasl
ASL Package Description: Array Support Library for IBM DS4800/DS4700/DS5000 and SUN ST6580/6780 Series Arrays in ALUA mode
ASL Package Version: 2.0
APM Package Name: VRTSLSIALUAapm
APM Package Description: Array Policy Module for IBM DS4800/DS4700/DS5000 and SUN ST6580/6780 Series Arrays in ALUA mode
APM Package version: 1.0
Supported versions of VERITAS Volume Manager: 5.0 RP5 and later
Supported Arrays: SUN ST6580/6780 Series Arrays in explicit ALUA mode (ALUA-LSI)

Note:
1. Please download the patch "5.0GARP5" for Volume Manager 5.0 on HPUX 11.31 from Symantec's VIAS site for the ASL and APM to function correctly.
2. On top of 5.0GARP5 patch, hotfix "5.0RP5HF1a" or later needs to be installed
3. VxFEN hotfix, "VxFEN-5.0RP2HF1" is required for fencing to work properly
4. On SUN ST6780/6580 array the Host mode should be set to HPTPGS
5. Minimum array firmware version required: 07:50:13:00
6. Disable HP-UX 11iv3 Native Multi-Pathing ALUA mode for Storage Foundation 5.0. Refer to the TechNote 330779 (link provided in the Related Documents section) for disabling Native Multi Pathing ALUA mode.

Installation Instructions:
1. Create a directory to download the ASL-APM package
# mkdir /tmp/asl_apm
# cd /tmp/asl_apm

2. At the bottom of this TechFile, click on Download Now to download the ASL-APM package

3. After downloading VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v2.tar_339355.gz, verify the checksum of the file
# cksum VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v2.tar_339355.gz
2965328642 85196 VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v2.tar_339355.gz

4. Uncompress the file and extract the packages
# gunzip VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v2.tar_339355.gz
# tar xvf VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v2.tar_339355

5. Before adding any package, ensure Veritas Volume Manager is installed and enabled
# vxdctl mode
mode: enabled

6. Install the ASL as follows:
# swinstall -s `pwd`/asl VRTSLSIALUAasl

7. Install the APM as follows:
# swinstall -s `pwd`/apm VRTSLSIALUAapm

8. After the packages are installed, you must execute the vxdctl enable command to claim the disk array
# vxdctl enable
Note: In some cases, it has been reported that the installation of the ASL does not take effect, and vxdctl enable does not claim the enclosure and devices. In such cases, you can execute the vxconfigd -k command in addition to vxdctl enable.

9. After executing vxdctl enable, verify the output of the vxddladm listsupport command
# vxddladm listsupport libname=libvxlsialua.sl
ATTR_NAME            ATTR_VALUE
=======================================================================
LIBNAME              libvxlsialua.sl
VID                  IBM, SUN
ARRAY_TYPE           ALUA-LSI
ARRAY_NAME           DS4800-, DS4700-, DS5100-
                   ST6580_6780-

10. Verify the ASL library version
# vxddladm listversion libname=libvxlsialua.sl
libvxlsialua.sl has version string: vm-5.0-rev-2. VXVM version: 5.0

11. Also verify the output of vxdmpadm listapm command. The APM should be in Active state.
# vxdmpadm listapm dmplsialua
Filename:               dmplsialua
APM name:               dmplsialua
APM version:            1
Feature:                VxVM
VxVM version:           50
Array Types Supported:  ALUA-LSI
Depending Array Types:  A/P
State:                  Active
