LTO tape device of autoloader

so.nimda — Thu, 11 Dec 2008 23:55:59 GMT

Hi,

How do I find the device name of the tape in an HP StorageWorks 1/8 Ultrium 960 Tape Autoloader?

When I run "ioscan -fnC tape", I get this :

Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
tape 0 0/1/1/1.2.0 stape NO_HW DEVICE HP C5683A
/dev/rmt/0m /dev/rmt/0mnb /dev/rmt/c3t2d0BESTn /dev/rmt/c3t2d0DDSb
/dev/rmt/0mb /dev/rmt/c3t2d0BEST /dev/rmt/c3t2d0BESTnb /dev/rmt/c3t2d0DDSn
/dev/rmt/0mn /dev/rmt/c3t2d0BESTb /dev/rmt/c3t2d0DDS /dev/rmt/c3t2d0DDSnb

which I don't think is referring to the LTO tape drive.

Can I assume that it's using the default "/dev/rmt/1m" or "/dev/rmt/1mn"?

Thanks !

Hi Nimda,

1. The Output
:>tape 0 0/1/1/1.2.0 stape NO_HW DEVICE HP C5683A
Shows that LTO Drive no hardware is present.

2. The Remaining details are for the DDS drive.

Check the connectivity once again.

Thanks,
Analyst.

Hi,

Yes you are write, Its refering to DDS tape drive

Can I assume that it's using the default "/dev/rmt/1m" or "/dev/rmt/1mn"?

NO you are wrong,

ioscan -fnC tape --> shows only /dev/rmt/0mn

dev/rmt/0m /dev/rmt/0mnb /dev/rmt/c3t2d0BESTn /dev/rmt/c3t2d0DDSb
/dev/rmt/0mb /dev/rmt/c3t2d0BEST /dev/rmt/c3t2d0BESTnb /dev/rmt/c3t2d0DDSn
---->/dev/rmt/0mn /dev/rmt/c3t2d0BESTb /dev/rmt/c3t2d0DDS /dev/rmt/c3t2d0DDSnb

Thanks

The tape you see as NO_HW is a DDS-4 drive.

Please give more info - what server model you have and where is the LTO connected?

Please post an "ioscan -fn", "model" too.

Hi all,

Sorry. Managed to get more info :

Data Protector Cell Manager is running on Server A and the Autoloader is connected to Server B. From Server B, doing "ioscan -fnc tape" reveal that the tape drive is "/dev/rmt/1m". Doing the same for Server A does not reveal that there's any tape drive.

Backups via DP of both Server A & B is done on the Autoloader successfully so far.

As I would like to carry out OS native backup on Server A, how do I identify the tape device?

Sorry for not being able to provide more info earlier.

Hope this makes more sense.

Thanks & regards
