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_v3.tar_346861.gz, verify the checksum of the file 
# cksum VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v3.tar_346861.gz
2372941335 92610 VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v3.tar_346861.gz

4. Uncompress the file and extract the packages
# gunzip VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v3.tar_346861.gz
# tar xvf VRTSLSIALUAasl_apm_HP11iv3_vm5.0_v3.tar_346861

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
PID                 All
ARRAY_TYPE          ALUA-LSI
ARRAY_NAME          DS4800-, DS4700-, DS5100-
                  ST6580_6780-, SUN6180-

10. Verify the ASL library version
# vxddladm listversion libname=libvxlsialua.sl
LIB_NAME                        ASL_VERSION      Min. VXVM version
===================================================================
libvxlsialua.sl                 vm-5.0-rev-3     5.0

11. Also verify the output of vxdmpadm listapm command. The APM should be in Active state.
# vxdmpadm listapm dmplsialua
