Mirrored NSS on SAN Problem

Hi,

we have got a strange problem:
When we are making a backup from a mirrored NSS Partition which is located
on 2 different SAN´s the Servers (Cluster) will freeze or go into an abend
(LZSS_* Modules). If we are breaking the mirror everything will work fine.
There are no errors on the Volume/Pool etc. The hardware doesn´t have any
failure.

Environment:

2 Node Cluster NW65SP4
each node: 2 HBA´s

Backup Server:
NW65SP4
2 Tape-Drives
Backup SW: Arcserve 11.1 or Backup Exec 9.1
Backup over LAN, with and w/o Agent

Any Idea is wellcome.
Thanks Thomas

Antw: Mirrored NSS on SAN Problem

Hi,

I have forgotten one additional information:

The mirror is a Software Mirror (RAID1).
The problem also occures when excessive Data is read from/written to the
mirrored volume (e.g. Read / write an image with zfd).

you might want to ask this in the cluster forum - but it sounds like you
need to update the drivers for the SAN hardware
