hi,

try to install the special device file for the tape:

# insf -H 10/1/4/0.3.0
and rescan
# ioscan -fnC tape
to verify if the device files are created.

regards.

To see the tape path for /dev/rmt/0m, use the lssf command:

lssf /dev/rmt/0m

However, if your ioscan command shows only one tape drive, then /dev/rmt/0m is meaningless or does not exist. If you add and delete peripheral devices without using rmsf, then new device file names will be automatically created. It doesn't matter what name is used (0m, 1m, 2m, 3m) as long as it points to the tape drive.

Dear Zungwon,

If /dev/rmt/0m dosent exist in the system and you need the device name, you can create it using

#mksf

command.

Please check the man page for complete syntax

# ioscan -fnC tape | grep '0m'

Information in H/W Path gives the Hardware path to you.

Or check with,

# lssf /dev/rmt/0m

It will give hardware informations along with others if existing else prompt with error that device is not there.

Hello,

You can use # ioscan -fnC tape and use lssf command with that. For more information, you can refer these threads,

Hi,

As the device listed in your initial post does have a device file allready linked to it with name /dev/rmt/c3t3d0BEST. The /dev/rmt/0mn may not be necessarily be linked to this device only. If you had some other drive configured at some other hardware address earlier than next device sequence will be assigned to this drive. The sequence should be
/dev/rmt/0m,0mn,0mnB
/dev/rmt/1m,1mn,1mnB
/dev/rmt/2m,2mn,2mnB
/dev/rmt/3m,3mn,3mnB
.
.
.
And so on
But here it seems that the same is not getting associated with it.The same can be resolved. As the device file is allready there I think you should remove device files and then reinsert them using insf.

#rmsf -H 10/1/4/0.3.0

#insf

HTH,
