Hi,
I have 2 servers (HPUX and Redhat) connected to 2 partitions on a Quantum i2000, the HPUX has 12 tape drives attached and Redhat (6) has 4.
I moved 2 of the tapes drives from Partiton1 (HPUX) to Partition2 (Redhat) which was successful and I can see 6 drives attached to Redhat and 10 to HPUX from the i2000.
My problem is that although I can see the 2 drives from robtest and /usr/openv/volmgr/bin/scan on the Redhat server they are not being discovered by the Redhat server itself. Ive done numerous Redhat rescans (I am a RHEL admin) but am still unable to see the 2 new tape drives.
Im told that I will need to reboot the Redhat box which I find strange as discovering new LUN's is straight forward but apparently discovering tape drives needs a reboot??
Any information or advice would be appreciated...
Except from /usr/openv/volmgr/bin/scan where HU1145KDDJ and HU1149KWK4 are the new drives.

tpconfig will only show what has been configured in NBU.
To see devices seen by OS, use
cat /proc/scsi/scsi
/usr/openv/volmgr/bin/scan -tape
(the output in your post shows what is seen from the robot itself, i.e. 'scan -changer')
If the OS sees all drives, re-run the Device Config wizard for this media server.

Thanks Marianne...
As I could see the tape drive from robtest and scan I thought everything was ok, after I looked at the switch config the WWN of the tape drive wasn't in the Redhat server zone so ive added the WWN to the zone and everything is good.
Check everything prior to raising an issue on the Symantec forum (!!) but appreciate the quick response..
Thanks..

Hi,
Please run the below OS command for detect the devices.
echo 1> /sys/class/fc_host/host1/issue_lip
/usr/openv/volmgr/bin/scan -tape
Thanks,
