ignite-ux ia64 with 1x8 G2 Autoloader

[Fred.B]

How would I go about creating an ignite tape on an HP-UX 11iV3 ia64 system that only has a 1x8 HP StorageWorks Autoloader? I realize I can simply remove 7 of the tapes to ensure that they are not over-written, and I know the device is /dev/rmt/4mn but do I need to specify a slot number, and if so how would that be done?

The tape must be manually loaded into the drive, ignite cannot do this.

If you are using DataProtector you might use the uma command to load the tape.

uma(1M)

uma - controls the robotics of SCSI compliant autochangers

Tape changers are actually two independent systems. One is the tape drive (or drives) and the other is the changer. You should always use the mc command to load the desired tape into the tape drive, perform your backup and then use mc to remove the tape. Some tape changers have automatic load options -- don't enable this feature for your system. mc works very well and is easy to use. The Data Protector uma command performs similar functions but mc is standard with HP-UX.

last question with regards to ignite. Can I run ignite with the system online (user accessable) or does it have to be done offline? Thanks for everyones help..

Use the "mc" command.
With mc command, you can command your jukebos, auto loader, tape library etc to do things for you like:

- find a media
- check if media is in the library
- check if drive is in use
- move media from slot to drive
- etc.

Do an "ioscan -kfnC autoch" to find the HP-UX device for you ronit firstly. Then use it as the "-p" argument in "mc":

i.e.:

mc -p /dev/rac/c10t0d0 -s S6 -d D1

moves Tape in Slot 6 to Drive 1



MAN "mc" -- there are even examples there.

You can run make_tape_recovery while the system is running. HOWEVER, the assumption is that you are selecting just vg00 and within vg00, there are no databases or other high activity files. The purpose of an ignite backup is to create a bootable image of the OS and backup of OS files -- nothing more. Here is the command you would use (after loading the desired tape):

make_tape_recovery -I -v -x inc_entire=vg00 -a /dev/rmt/0mn

where: /dev/rmt/0mn is the tape drive you want to use.

I'm having difficulties with the mc command so I did a 'ioscan -C tape -fn' which returned the following:

Class I H/W Path Driver S/W State H/W Type Description
==================================================================
tape 4 0/5/1/0/4/0.4.0 stape CLAIMED DEVICE HP Ultrium 2-SCSI
/dev/rmt/4m /dev/rmt/4mn /dev/rmt/c2t4d0BEST /dev/rmt/c2t4d0BESTn
/dev/rmt/4mb /dev/rmt/4mnb /dev/rmt/c2t4d0BESTb /dev/rmt/c2t4d0BESTnb

I know that with ignite I have to specify no-rewind so I tried the following command:
mc -p /dev/rmt/c2t4d0BESTn -s S8 -d D1
and got this:
ERROR: 0x5 Illegal Request : 0x2400 Invalid field in command descriptor block
If I understand this correctly it should have moved the tape in slot 8 to drive 1. I tried the same command using 4mn and got the same result. I noticed in HP Data Protector (HPDP) that the changer robotics uses /dev/rchgr/autoch5 and the drive in HPDP says /dev/rmt/4mn

So what am I doing incorrectly? Thanks again..

[Alzhy]

Have you done:

ioscan -kfnC autoch

to find out your robotics/autochanger loader device?

[Alzhy]

You DO NOT use a tape drive device as argument (-p) to the "mc" command good sir.

Post the result of your "ioscan -kfnC autoch" please. That will tell us if your robotics is even seen by the OS.
