HP CE-ASSIS saids that booting from ignite tape isn't supported

Hi,

I'm trying to boot a vPar from an ignite tape. The vPar has a DDS unit (dev/rmt/5mn) but the thing is when the vPar is booting it was unable to "see" such device within the EFI Shell and therefore it can't boot from there. So I decided to open a service call in HP and it was assigned to a CE-Assis who without regarding any information from me simply saids that what i was trying to do isn't supported. He saids that I first have to boot from DVD and then recover from the tape. I have (from swlist):

HP-UX version: HPUX11i-OE-Ent B.11.23.0712 HP-UX Enterprise Operating Environment Component

vPars version: T1335BC A.04.06 HP-UX Virtual Partitions for 11.23

Ignite version: IGNITE C.7.6.98 HP-UX Installation Utilities (Ignite-UX)

I think that with this configuration booting directly from an ignite tape id in deed supported, but I'm not sure.

So i want you to help me to know if this guy is right or not and then try to resolve my issue.

If more information is required just let me know.

Regards.

Re: HP CE-ASSIS saids that booting from ignite tape isn't supported

AFAIR the support for booting a vPar directly from tape came with 4.03 - need to check tis again.

Since you cannot interact with EFI in vPars environment, you need to setup each vPar to be able to boot from tape.

(see vparmodify ... -a io:...:TAPE)

Hope this helps!

Torsten.

Will check it.

From 4.03 manual:

Using make_tape_recovery within a vPars-environment on PA-RISC Servers
(vPars A.03.03, A.04.03)

...

# vparmodify -p winona2 -a io:1/0/14/0/0/4/0.5.0:TAPE

...

winona1# vparboot -p winona2 -B TAPE


Of course your server must have a minimum firmware version.

Hope this helps!

Torsten.

I'm testing it today. The system meet the firmware revision required to install vPars 4.06

Re: HP CE-ASSIS saids that booting from ignite tape isn't supported

From the most current manual:

For PA-RISC servers, vPars supports tape drives beginning with vPars A.03.03 for HP-UX 11i
v1, vPars A.04.03 for HP-UX 11i v2, and vPars A.05.01 for HP-UX 11i v3. This includes recovery
of a virtual partition within a vPars environment and without using an Ignite-UX server as a
boot helper.
For HP Integrity servers, vPars supports tape drives beginning with vPars A.04.04 for HP-UX
11i v2, and vPars A.05.02 for HP-UX 11i v3, including recovery of a virtual partition within a
vPars environment and without using an Ignite-UX server as a boot helper.

Good one Torsten,

I will e-mail the link to this page to the CE-Assis, I hope this clear his mind and then focuss our efforts to resolve the issue.

Re: HP CE-ASSIS saids that booting from ignite tape isn't supported

Can you tell some more about your problem?

You cannot have EFI access while the vpmon is booted.


Did you configure the vPar to be able to boot from tape?

What exactly is your problem?

Hope this helps!
Regards
Torsten.

See the attached file (word document with 2 images), I hope it will be fully clarified with this.

You wrote

"vPar1 canâ t scan such device unless you unplug a disk device from the HBA to which the tape device is connected (there isnâ t a C7438A device)"

You have disks and tapes on the same bus?

If you unplug a specific disk, the tape can be accessed? Did you check for SCSI ID conflicts?

Hope this helps!
Regards
Torsten.

I assume I'm ussing A6961-60011 which is a dual port scsi hba, one port is used by the disk defined as an alter boot path and the other is used with the tape array. Already I have tested several combinatios between this two ports and the only one that let me see the C7438A device is unplug the disk cable and let alone the C7438A cable.

Re: HP CE-ASSIS saids that booting from ignite tape isn't supported

By the way in the other vPar i have a similar configuration (both tape and disk connected to the same hba) and it works just fine.

Re: HP CE-ASSIS saids that booting from ignite tape isn't supported

Depending on your config you can include only one part of a combo card by configuration.

Please check (and post) your config (vparstatus -v) together with an ioscan -fn.

Hope this helps!

Torsten.

Re: HP CE-ASSIS saids that booting from ignite tape isn't supported

Forgot to said that both vPars share the same tape array: when needed turn off the tape array, unplugg it from one vPar and connect it to the other, then turn on again the tape array.
