Question
Unable to restore from HP Data Protector / Omni Back
We have a problem with HP Omniback / Data Protector. We are able to reliably backup 700 GB ( confirming seven hundred gigabytes ) of data on a regular basis.
We are able to restore selected individual files from this backup without any problems.
When we attempt to restore all of the data from a full backup, the process will fail at some point anywhere from say 90 GB of the way through to 400 GB of the way through. The error message upon failure of the restore process is:
[Major] From: RSM@hostname "" Time: 23/05/2005 10:03:57 a.m.
[61:3003] Lost connection to Filesystem restore DA named ""
on host hostname.
Ipc subsystem reports: "IPC Read Error
System error: [10054] Connection reset by peer
"
( "hostname" has been substituted for the real server name in the above error message )
We have tried breaking the 700 GB of data into smaller restore sessions, however the problem persists.
We have recently been upgraded, by HP, from Data Protector V5.0 to Data Protector 5.5. Note that the names "Data Protector", "OmniBack" and "OpenView Storage Data Protector" all reference the same backup software in case it is known by other names elsewhere.
Our environment can be summarised as follows:
Windows 2000 server with SP4 applied
HP Server Hardware
HP Omniback version 5.5 with patches DPWIN_00111, DPWIN_00112 and DPWIN_00113 applied
HP SDLT1 tape drive direct-attached via SCSI to server hardware
HP MSL5026 tape library
1 Gbps switched network
We have been working closely with HP on this problem for a couple of months now, and so far they have not been able to determine a cause for this issue.
HP have suggested that we have a DNS / name resolution issue, however we and they have checked this and have not been able to find any problem with DNS.
HP have suggested a networking / IPC problem, however again no specific issue has been found.
The issue has been escalated within HP to their internal development labs.
My question is, has anyone seen this issue, and if so, can they advise a course of action to fix it ?
