Repeated drive failures and backup highlighting 2009
- 10 years ago
If drives are constantly going down, you first of all need to find the reason.
Deleting and re-discovering devices will fix device mapping issues, but not underlying hardware or driver or OS/device comms issues.
NetBackup needs the OS for I/O and device comms.
Therefore all troubleshooting should start at OS level.Check Linux /var/log/messages file for hardware issues and Windows Event Viewer System logs.
To see why drives are being Down'ed, add VERBOSE entry to vm.conf on all media servers.
/usr/openv/volmgr/vm.conf on Linux server
....\Veritas\volmgr\vm.conf on Windows server
followed by restart of NBU after adding this entry.Exact reason for drives going DOWN will be logged to Linux /var/log/messages file and Windows Event Viewer Application log.
Create bptm log folder under netbackup/logs on all media servers to trace I/O errors from NBU point of view.
