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


2 Node Cluster NW65SP4
each node: 2 HBA´s

Backup Server:
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
