At teh command prompt on the Media Agent 'rocsrv', run the command
devbra -dev
Normally, this will output fields for Tape Drives 'Tape' and the robotics 'Exch' similiar to this:
Tape HP:Ultrium 3-SCSI Path: "/dev/rmt/0mn" SN: "HU10938F7R"
Description: HP LTO3 Drive
Revision: D23W Device type: lto [13] Flags: 0x0001
Exch HP:1x8 G2 AUTOLDR Path: "/dev/rac/c0t4d1" SN: "MXA94210HN"
Description: HP StorageWorks 1x8 Cartridge Autoloader
Revision: 2.80 Flags: 0x0006 Slots: 7 Drives: 1
Drive(s) SN:
"HU10938F7R"
I think that, when you run this command, you will be missing the' Exch' field, or, if it is ther, you will see a lot of 'N/A' entries
If your media agent is HPUX, run an
ioscan -fn
and look for any 'Autoch' types. If the media agent is Windows, go to the Devcie Manager, and see if you see any Media Changers
Tis may require a system reboot on either type of server to go out and idnetify SCSI-attached devices
If you are in a SAN, make sure that your zoning is correct
This may also be a problm with physical connections (cables, SCSI-intderfaces, terminators) between the server and the Tape library
'devbra' is your friend
