[Networker] Summary: Netapp NDMP backups with NW7.0
2003-07-02 13:36:59
Folks,
I seem to have Networker working, but I won't hold my breath.
Symptoms:
When mounting a tape in NDMP device and verifying label the following
error occurs (/nsr/logs/messages):
Jun 30 18:00:32 nickel logger: NetWorker media: (info) ndmp tape mtio
failed, I/O error
The tape is then marked full and another tape is used.
Details:
NW 7.0 Build 322 Network Edition
RH 7.2 (kernel 2.4.18-17.7.x) on Dell Poweredge 2550
Spectralogic 10K (scsi, 40 slots, 4 drives
2 AIT-2 drives connected to NetApp
2 AIT-3 drives connected to NetApp
NetApp 720 (6.2R2)
Here is what I changed:
- eject/sleep/unload sleep times of 90 seconds (decrease from 120)
- change NDMP from version 3 to version 4 on Netapp
I have not yet tested to see whether any of these tapes are readable. I
suspect that the "prematurely full" tapes will be unreadable.
I am still uneasy about this. Yesterday I did a "nsrjb -HEv" and the linux
box hung. There are no messages anywhere to indicate what the problem is.
And I got a weird error (once) when running NDMP backups where backups were
running fine and then the NetApp decided that it was unable to connect or
authorize the client for the second NetApp and quit. This was after
successfully backing up 3 of 9 qtrees.
I will open a case with Legato when I have some other fires under control.
