StorageTek Proprietary

Storage System Configuration

and the access volume is visible, it will corrupt access to the

StorageTek array. Check if the packages are installed by running the

command:

lslpp -L devices.fcp.disk.array.*

If there is no IBM storage array connected in the architecture, we

recommend removing the AIX packages as follows.

installp -u devices.fcp.disk.array.*

This will allow you to map and use the access LUN for inband storage

management operations if you chose. If AIX software patches are

applied, check if the packages were reinstalled and remove them if

they were.

Upgrading an Existing Configuration

If upgrading an existing storage system that is installed and configured on AIX,

or upgrading software on the AIX host; perform the following actions to

remove existing devices on the AIX host prior to doing any software

modifications. A complete backup of data should be performed prior to this

procedure.

If any of the following steps do not complete and indicate device

busy, do not proceed until the application that is using the device

is stopped. For example you may need to do an SMagent stop

command to stop usage of the access LUNs, stop file system

access by applications, or cd out of a mounted file system. All

devices must be successfully unmounted, varied off, and removed

prior to continuing with software upgrades, otherwise major host

corruption will occur.

1. Unmount any mounted file systems using the umount command or

smit

2. Vary offline any volume groups using varyoffvg or smit

3. If using inband storage management, run the following command.

SMagent stop

4. If using Cambex DPF failover driver, run the following command.

stopsrc -s cbxdpfar

5. Determine the HBAs being used by using the lsdev –Cc adapter

command.

6. Remove the adapters and scsi devices using the rmdev –Rdl fcs(n)

for IBM HBAs, or rmdev –Rdl fscsi(n) for Cambex HBAs

Example for an IBM HBA
