Help on tape drive status

Viswanadhan — Fri, 04 Jan 2008 14:27:09 GMT

Hi Admins,

I have hp ux with 11.0 Ver. In this server tape drive configured, and working fine.When i say

# mt -f /dev/rmt/0m status
mt: unknown command "status"

May i know the reason for above error. Do it need to install any depot / SD ?
Let me know the SD / Depot name, and where can i get it.

Regards,
Viswa.

Once upon a time HPUX mt command did not have the status option. Is it listed in the 11.0 man pages ?

Works for me on an 11.0 server:

servera:root /root # mt -f /dev/rmt/c0t0d0DDS status
Drive: HP C1537A
Format:
Status: [0]
File: 0
Block: 0

For few server
# mt -f /dev/rmt/0m status

is working.

For few servers "mt -f /dev/rmt/0m status" command is not working.

all HP UX are with 11.0 ver.

If you do:
servera:root /root # mt
usage: mt [ -f tapename ] command [ count ]
command is one of:
eof, fsf, bsf, fsr, bsr, rewind, offline, eod, smk, fss, bss, reserve, release, status

Does that one show the status as an option?
Any chance you have some odd hidden chars like some weird backspace chars while typing the command due to termtype being off?

Hi,

# which mt
/usr/bin/mt

I got same result for all HP UX servers.

To follow up on what Roberto suggested, you would want to run the second suggested command:
servera:root /root # what /usr/bin/mt
/usr/bin/mt:
$Revision: 82.2.1.2 $
PATCH_11_00: mt.o 98/10/20

you should try a "which mt" and a
/usr/bin/mt -f /dev/rmt/0mn status

and a what /usr/bin/mt

Hi All,

Now i got the difference between HP UX servers with 11.0ver.

Server1# what /usr/bin/mt
/usr/bin/mt:
$Revision: 82.2 $

Server2# what /usr/bin/mt
/usr/bin/mt:
$Revision: 82.2.1.2 $
PATCH_11_00: mt.o 98/10/20

Where can i get the patch for mt command. May i know the url ?

Regards,
Viswa.

to check what patch is it do a swlist -l file |grep /usr/bin/mt

From the patch readme of PHCO_16748:

mt:
1. Enhancement - status option
2. Enhancement - reserve/release option for shared devices

http://www12.itrc.hp.com/service/patch/patchDetail.do?patchid=PHCO_16748&sel={hpux:11.00,}&BC=main|search|

But instead of patching unsupported systems you should consider to get at least 11.11 installed.
