Upgrade Installation
If you are currently using an AIX server in transparent failover mode, and you wish to upgrade
to ACS Version 8.7P in a DRM environment, follow these instructions.
Upgrade Installation Assumptions
■ All components are connected
■ AIX OS is upgraded to v4.3.3 or v5.1
■ Cambex Fibre Channel adapters are installed
■ A version of Secure Path is loaded
■ A version of the solution platform kit is loaded, or has been upgraded
■ HSG80 ACS code is being upgraded to v8.7P
■ Storage subsystem is pre-configured with or without a CCL LUN, in SCSI-2 or SCSI-3
mode, with the LUN connection type set as WINNT
■ HBAs are installed in pairs
■ Volume groups, logical volumes, and file systems created
■ Clustering services may be installed
HBA Limitations
HBAs have the following limitations:
■ Addressing of LUNS is limited to 16 devices. This limitation must be considered when
planning the subsystem storage configuration.
■ Configuring a CCL LUN will leave 15 LUN addresses.

volume groups, with the following commands:
#umount /dev/(logical_volume_name)
#fsck /(file_system_name)
#varyoffvg (volume_group_name)
I 6. Remove all hdisks associated with DEC HSG80 RAID array from the configuration
database with the following commands:
#lsdev -Cc disk
#rmdev -dl hdiskx (x is the hdisk number)
