Veritas NetBackup™ Snapshot Client Administrator's Guide

Limitations of using HP-UX 11.31

HP-UX 11.31 does allow a new device to be present on the same SCSI path on which different device was visible to the host. During the snapshot process, when the old snapshot is deleted and a new snapshot is created, the new snapshot appears on the same SCSI path as the older snapshot. That causes a conflict within the HP-UX system and it logs an error message.

During a snapshot with NetBackup installed on a computer that has HP-UX 11iv3 installed, the Syslog error messages are similar to the following:

class : lunpath, instance 15
Evpd inquiry page 83h/80h failed or the current page 83h/80h
data do not match the previous known page 83h/80h data on
LUN id 0x0 probed beneath the target path (class = tgtpath,
instance = 4) The lun path is (class = lunpath, instance 15).
Run 'scsimgr replace_wwid' command to validate the change

The administrators of the HP-UX 11iv3 host machines should ignore the log messages if they encounter them during backups with NetBackup.
