tape devices unavailable
Hi,
I have a trucluster(three member cluster) 5.1b pk4, where the connection from the server to the drives are via a san switch to a NSRouter, connected to two MSL5000 series autochangers (1master & 1 slave). Using in total of 8 SDLT320 drives.
The Backup software is NetWorker v7.1.2.
We have been a lot of issues lately where the driver owner number is set to 4 on one member. Some of the things i see are:
# hwmgr -view hier -id 445
HWID: hardware hierarchy (!)warning (X)critical (-)inactive (see -status)
-------------------------------------------------------------------------------
445: X tape bus-3-targ-2-lun-1 tape0
# hwmgr status comp -id 445
STATUS ACCESS INDICT
HWID: HOSTNAME SUMMARY STATE STATE LEVEL NAME
------------------------------------------------------------------------------
445: critical online unavailable tape0
However when i run the same command on another member everything comes back ok.
I have run:
hwmgr refresh comp
hwmgr refresh scsi
hwmgr scan scsi
across all three members.
Here we go, is there anyway without a reboot :) where the tape devices can be re-initialised through a hwmgr command? I've been looking through manuals and nothing seems to work for these tape devices. I may have missed something?
I have also had the autochangers power-cycled
Cheers,
Erkan.

Re: tape devices unavailable
Is the KGPSA (dedicated to tape traffic ?) on this server still OK, ie: see binary.errlog ?
Is switchport OK, is zoning on switch still OK, see SupportShow on switch ?
Is the NSR's mapping still OK, firmware up-to-date ?

Re: tape devices unavailable
It seems that you lost connection with the tape device, I get that output when I remove the device from the system.
What is the output of hwmgr show scsi?
126: 16 tape none 0 1 tape0 [0/3/0]
127: 3 tape none 0 1 tape6
Tape0 has a valid path and tape6 does not. This is because I have lost the connection with tape6.
If you delete the device:
hwmgr delete -id 445
And then run hwmgr scan scsi, the device appears again?

Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: tape devices unavailable
Thanks Ivan, although this is not the case.
Johan, the NSR mapping is ok, and the firmware is all up to date.
I will check on your other suggestions though.
Thanks,
Erkan.
