Re: HELP needed. Can't use rmt3 & rmt4 for SAN backup.

Ameerul,

You should make sure that the drives maps are exact. E.g. when drive rmt1
on clientA maps to rmt3 on tsmsrv you should make sure that whne you
define the tape path for clientA that you use the correct drive within TSM
(that is the DRIVE for rmt3), the physical device is however /dev/rmt1
(the device on clientA).

Hope this helps. If not please mail the output of lscfg -vl rmt1 (from
clientA) and lscfg -vl rmt3 (from tsmsrv) and the output of q path f=d.

Richard.

        Subject:        HELP needed. Can't use rmt3 & rmt4 for SAN backup.


Hi All,
I have this scenario on the TSM server:
-TSM Svr 5.2.3
-TSM Client 5.2.2
-TSM SAN 5.2.2
-Tape library 3584 LTO with 4 drives

I have another clientA with SAN attached. It can see
(lsdev -Cc) the 3rd and 4 th drive of the 3584. 1st
and 2nd is by another clientB.

For clientB, after configuring the storage agent and
test the backup, it manage to backup nicely thru
LAN-free with no error.

For clientA, after configuring, tested the backup, it
gives error=46 on the dsmsta, could not mount tape.
But the Tsm serverconsole, a drive has been
mounted(different drive).Why is this?

For client B,on the tsm server i configured the path
for drive to /dev/rmt1 and /dev/rmt2 same as clientA
since that is what is seen using lsdev -Cc tape for
ClientA and ClientB.

The difference for both client is that for clientB
rmt1 on clientB maps excatly to the tsmsvr rmt1. This
is check with lscfg -vl rmt1. But for clientA rmt1
maps to rmt3 of tsmsvr.

The rmt is configured that way to separate the load of
backups for clientA and clientB on to the tape drives.

Pls help me to resolve this.

Thanks and best regards
Ameerul Madzali
