Hi Tony,

Here is the info on NetBackup Media Manager's logs a) The log under /usr/openv/netbackup/logs/user_ops/dbext/logs directory shows the following: 09:10:11 (197975.001) INF - Beginning restore from server phx00bs2 to client phx00apt1. 09:50:35 (197975.001) Status of restore from copy 1 of image created Mon Feb 27 19:09:01 2012 = the restore failed to recover the requested

b) The log under /usr/openv/netbackup/logs/dbclient directory shows the following:

09:59:40.758 [6456] <4> VxBSASetEnv: INF - entering SetEnv - NBBSA_CLIENT_READ_TIMEOUT
09:59:40.758 [6456] <4> VxBSAGetEnv: INF - entering GetEnv - NBBSA_CLIENT_READ_TIMEOUT
09:59:40.758 [6456] <4> VxBSAGetEnv: INF - returning - 10800
09:59:40.758 [6456] <4> dbc_SetClientReadTimeout: INF - sending client read timeout

09:59:40.758 [6456] <8> int_ReadData: WRN - Failed to set client read timeout.
09:59:40.759 [6456] <2> sbterror: INF - entering
09:59:40.759 [6456] <2> sbterror: INF - Error=7504: Got end-of-file

d) /usr/openv/netbackup/logs/bphdb directory didn't have any log.

e) When I googled with "WRN - Failed to set client read timeout" I found the Article TECH73065 and Article: TECH53002 from Symantec site and these suggests me to verify the media Mount Timeout. Our storage administrator verified that it was set to unlimited. <phx00bs2><root>bpconfig -U | grep -i mount Media Mount Timeout: 0 minutes (unlimited) Shared Media Mount Timeout:0 minutes (unlimited)

Let me know if any other are I should look at.

Reposted due to overquoting..

Did you check the NetBackup Media Manager's logs? Perhaps it is trying to read from a tape that is not (no longer) mounted? Those logs should be on the NetBackup Media server, not necessarily on the database host (depending on your setup, of course).
