Getting media write error from a particular media server

[Sharad_Singh7]

Hello All,

I am facing error 84 from a media server particularly from a drive. When I checked the logs I found below:

Nov 23 19:08:47 p02danbs04 acsd[25036]: [ID 857816 daemon.error] Fatal open error on OC9940B_a1p02d07 (device 13, /devices/pci@82,2000/fibre-channel@1/fp@0,0/sg@w500104f0006fae27,0:raw), errno = 19 (No such device), DOWN'ing it

Media server OS:  Solaris

Netbackup Version : 6.5

The OS has lost connectivity to the tape drive.

Check devices at OS level with cfgadm -al.

Check /var/adm/messages for errors.

Only when you can locate the /dev/rmt/###   sym-link that corresponds with above /devices... address and this command is successful :
mt -f /dev/rmt/### status
(Should return: no tape loaded or device offline)
can we help you to re-add it in NetBackup.

At this point you do not have a NBU problem.
Troubleshoot device -> OS connectivity.

PS:
You need to upgrade!
NBU 6.x ran out of support more than 2 years ago.

Do you see this drive in OS level and scan level

check the below command 

scan 

tpautoconf -t

and tpconfig -d

and make sure the drives that are displayed in tpautoconf and tpconfig are with correct paths..
