rx8640 with expansion cabinet

[J Turner]

I have been ask why we do not have more vpars available on our rx8640 with expansion cabinet. Currently we have 2 npars w 2 vpars each. If we can create more npars/vpars can anyone help with the commands needed I ran some commands and here is the output.

It looks from the scan at the end of this output that we have used all the resources except the cpu's. This would mean no hard drives for vparcreate?

[Torsten.]

The expansion cabinet will give you more I/O slots and more internal disks.

If you already use all available internal disks, you may consider to boot additional vPars from external disks (direct SCSI connected or fiber channel).

What result gives

vparstatus -A

And some more information please:
vparstatus -v
parstatus
olrad -q

(capture and attach to get a better formatting)

Here is the output. Thanks for the quick replies.

[Torsten. · Accepted solution]

You did the assignment of I/O on SBA level (not on LBA level), that means all available I/O is already assigned.

npar0
vpar0
(all) IO on 0.0

vpar1
IO on 3.0

npar1
vpar0
IO on 1.0

vpar1
IO on 2.0


IMHO not the best design. I would use each time one slot from IO chassis and one from another.


As long as all IO is assigned, you have no more resources to distribute.

[Torsten.]

And from the olrad command I assume all slots in the main chassis are full, but you did not provide this information for the expansion chassis.

[J Turner]

I inherited this machine and two of the vpars are in production.
I though the same thing as far as not having resources to use.

Thanks for the second opinion.

[J Turner]

Last question.
Without enabling the MP port on the expansion cabinet (It is in a secure facility with very limited access) is there anyway of getting the output for the populated slots!

Thanks...

[Torsten.]

The master MP in the main chassis is your interface to all of the hardware, but the MP does not know much about the cards in the slots.

If your vPars are already up and running, run "olrad -q" on them. If you see a power state up, there is a likely card installed.

[Torsten.]

(pressed submit too quickly)

An "ioscan -fn" will tell you.
If there is an lba device and nothing below on this particular path, the slot is empty.

[J Turner]

Thanks
