Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

First obtain the appropriate firmware upgrades from your disk drive vendor. You

can usually download the appropriate files and documentation from the vendor’s

support website.

To upgrade the disk controller firmware

Disable the plex that is associated with the disk device:

# /opt/VRTS/bin/vxplex -g diskgroup det plex

(The example is a volume mirrored across 2 controllers on one HBA.)

Stop I/O to all disks through one controller of the HBA:

# /opt/VRTS/bin/vxdmpadm disable ctlr=first_cntlr

For the other controller on the HBA, enter:

# /opt/VRTS/bin/vxdmpadm -f disable ctlr=second_cntlr

Upgrade the firmware on those disks for which the controllers have been

disabled using the procedures that you obtained from the disk drive vendor.

After doing the upgrade, re-enable all the controllers:

# /opt/VRTS/bin/vxdmpadm enable ctlr=first_cntlr

# /opt/VRTS/bin/vxdmpadm enable ctlr=second_cntlr

Re-enable the plex associated with the device:

# /opt/VRTS/bin/vxplex -g diskgroup att volume plex

This command takes some time depending upon the size of the mirror set.

Renaming an enclosure

The vxdmpadm setattr command can be used to assign a meaningful name to an

existing enclosure, for example:

# vxdmpadm setattr enclosure enc0 name=GRP1

This example changes the name of an enclosure from enc0 to GRP1.

Note: The maximum length of the enclosure name prefix is 25 characters.

The following command shows the changed name:
