Hi, I have the same problem

My configuration:

Server Legato: AIX 5.1
Legato  7.1 Build 230

SAN Components:

Router Crossroads 10000
Switch SilkWorm 3200
Library L700 with seven SDLT3200

The seven units share by four nodes (3 AIX and 1 Tru64)


Best regards

The NSR from HP can block SCSI bus resets.
