Three command line restores are successful if run one at a time.
It is desired to run them simultaneously.
Environment info
HP V2500 - 11.0 with 12 GB memory (this box is the master server)
StorageTek L700 4 DLT tape drives connected via tape SAN (Fiber topology)
Netbackup 4.5FP3 NUMBER_DATA_BUFFERS=16 SIZE_DATA_BUFFERS=65536
command syntax
bprestore -L <logfilename.1> -C <client> -s <startdate> -e <enddate> -f
<file list.1>
bprestore -L <logfilename.2> -C <client> -s <startdate> -e <enddate> -f
<file list.2>
bprestore -L <logfilename.3> -C <client> -s <startdate> -e <enddate> -f
<file list.3>
The resulting observations
3 restores are started locally, on this V class, one right after another
(the 3 restores are running simultaneously on this box). The 3 tapes are
mounted, positioned, and the restores start. Whichever restore to start
first will run successfully, the other two fail with an error code of 5.
These separate restores may be attempting to write to the same
filesystem/directory simultaneously. Methinks that would be the problem.
Log information
Unfortunately, I do not have any log information from this DR exercise.
Next exercise I will get at least the following logs and others that may be
suggested:
all logs report
bptm
bpbrm
Request
Any suggestions/comments about this would be appreciated.
