Hi managers,
We are trying to configure a MSL5052 (4 Drives SDLT 110/220) to be added to our SAN for backups.
We are running Compaq Tru64 UNIX V5.1 (Rev. 732), patch kit3 as part of a 2-node cluster.
The Legato server is under Windows 2000 Server, and the two nodes of the TruCluster are considered as Storage nodes.
The problems are:
1) On the TruCluster nodes, when I run a vdump command on the drive, I get an I/O error to retry press yes, when I do yes: the backup continue.
# vdump -0f /dev/ntape/tape18_d1 /
path : /
dev/fset : cluster_root#root
type : advfs
advfs id : 0x3b3a2426.000d3d03.1
vdump: Date of last level 0 dump: the start of the epoch
vdump: Dumping directories
vdump: Dumping 121911479 bytes, 278 directories, 5386 files
vdump: Dumping regular files
vdump: unable to write to device </dev/ntape/tape18_d1>; [5] I/O error
vdump: do you want to retry? Y
vdump: unable to write to device </dev/ntape/tape18_d1>; [5] I/O error
vdump: do you want to retry? Y
vdump: Status at Wed Jun 4 17:10:49 2003
vdump: Dumped 122169710 of 121911479 bytes; 100.2% completed
vdump: Dumped 278 of 278 directories; 100.0% completed
vdump: Dumped 5386 of 5386 files; 100.0% completed
vdump: Dump completed at Wed Jun 4 17:10:49 2003
When I try to backup files with tar command, there is no I/O error.
Does anyone have any ideas? I took a look at the hwmgr output and I don't see any problems:
# hwmgr -view dev

Under windows server there is no problem.
2) When I try to do a backup under networker, the backup is stopped and I have a message explaining that the "media is full"
juin 04 16:25:48 backup-srv: NetWorker Media: (info) loading volume GNA858 into rd=alpha:/dev/ntape/tape19_d0
juin 04 16:27:04 backup-srv: NetWorker media: (warning) rd=alpha:/dev/ntape/tape19_d0 writing: I/O error, at file 2 record 378

juin 04 16:27:04 backup-srv: NetWorker media: (notice) sdlt tape GNA858 on rd=alpha:/dev/ntape/tape19_d0 is full

juin 04 16:27:33 backup-srv: NetWorker media: (info) Labeling a new writable volume for pool 'Prod'
Can anyone suggest any further diagnosis that I might do to establish what is going wrong?
Thanks in advance,
