BPTM log (/usr/openv/netbackup/logs/bptm) to just stop immediately after attempting to read the tape information after the mount -

Cause

NetBackup 7.0.1 introduces the ability to perform multiplex backup of remote NDMP servers.
The 6.5.x media server is not capable of performing a multiplex NDMP restore.

 

In the bprd log (/usr/openv/netbackup/logs/bprd) determined that there was a media server at NetBackup 6.5.2 level in this environment -

12:00:40.960 [24775] <2> local_getHostInfo: platform of client 2ksewrwww1.tak.bup is Linux, RedHat2.6
12:00:41.030 [24775] <2> bpcr_get_uname_rqst: bpcr.c: 3777 count=22, buffer=UNAME_SYSNAME = Linux
12:00:41.030 [24775] <2> bpcr_get_uname_rqst: bpcr.c: 3777 count=43, buffer=UNAME_NODENAME = 2ksewrwww1.taketwo.online
....
12:00:41.310 [24775] <2> getPatchLevel: level = >6.5.2<

Solution

Per TechNote TECH145842 the workaround was to create NON_MPX_RESTORE touch file on the master server. This did not work in this case.

Only applying engineering binary for ET2245820 resolved the problem.


Applies To
