Hello,
I am a fairly new admin.
I have installed a Host Bus adapter and tape drive on 3 different machines
(2-RX6600 and 1-RX3600) All 3 machines respond the same to:
# mt -f /dev/rmt/0mn status
no tape loaded
Below are a few details on the RX3600:
HP-UX 11i V3
RX3600
Installed HP SC44Ge Host Bus Adapter
(CommonIO B.11.31.1103.01)
Installed HP LTO-5 3000 SAS Driver (external 1U rackmount)
# ioscan -fnC tape

Replaced that tape with another new one, but got the same result.

Re: No Tape Loaded for mt status
Are the tape units autoloaders or standalone tape drives? Try installing HP's Library and Tape Tools on one of the hosts. This tool might give you more information about the drives and can test the ability to connect to the drive from the host.

It appears that the hardware is fine, so it must be something I'm doing wrong on the command line.

SolutionThen perhaps this is a SAS driver issue or patch issue. You show your CommonIO package version, is it the latest?
Search software.hp.com for this and also for sasd and check results.

Re: No Tape Loaded for mt status
Also, perhaps try the persistent DSF:
# ioscan -m dsf
Look for the equivalent device file that give that a shot.

Re: No Tape Loaded for mt status
The behavior of the command is strange. I wonder if this has anything to do with the tape using the stape driver rather than the estape driver (or if it matters)?
Do you have the estape driver loaded into the kernel? (lsdev). However, not sure about how to associate a device with a different driver (I think this can be done?)? I dont time now to research, so maybe someone else can offer help on this topic?

Re: No Tape Loaded for mt status
OK... I'm still at :-)
Yes it looks like I have both drivers loaded...
HPPRODWEB01:/# more /stand/system | grep -e tape
module estape best 1.0.[45D4D120]
module stape best 1.0.[45D4D134]
I used rmsf instead of rm to remove the /dev/rmt/ device files this time...
HPPRODWEB01:/# rmsf /dev/rmt/*
HPPRODWEB01:/#
Which worked, but this didn't...
HPPRODWEB01:/dev/rtape# rmsf /dev/rtape/*
Device /dev/rtape/tape1_BEST is busy. Cannot remove.
Device /dev/rtape/tape1_BESTb is busy. Cannot remove.
Device /dev/rtape/tape1_BESTn is busy. Cannot remove.
Device /dev/rtape/tape1_BESTnb is busy. Cannot remove.
so I ran...
HPPRODWEB01:/dev/rmt# insf -e -C tape
insf: Installing special files for stape instance 0 address 0/6/0/0/0/0/1/0/0/0.0.0.0.0
insf: Installing special files for estape instance 1 address 64000/0xfa00/0x4
So I ran these ioscans...
HPPRODWEB01:/# ioscan -fNnC tape

I'm a little confused now, so any help would be greatly appreciated.
