Enable Disks from other cell board

Hello Everyone,

I have a rp7420 using both cell boards with only one partition. As you may know, you can put up to 4 internal disks. We currently are using 2 but would like to use the other 2. The issue is that when I add the disks, it can't be seen with ioscan. I believe I have to activate those slots using parmodify but I've never done that so I have no idea where to begin.

Your help is greatly appreciated...

Re: Enable Disks from other cell board

You need a second pair of core io, do you have this?

Hope this helps!

Torsten.

Re: Enable Disks from other cell board

Yes, I do have the other core I/O

Here's the output for parstatus:

Notes: N+ = There are one or more spare items (fans/power supplies).
N = The number of items meets but does not exceed the need.
N- = There are insufficient items to meet the need.
? = The adequacy of the cooling system/power supplies is unknown.

Re: Enable Disks from other cell board

No, obviously not.

cell 0 is not core capable, hence no disks.

Hope this helps!

Torsten.

Re: Enable Disks from other cell board


Modify the nPartition core cell choices using the parmodify -p# -r#... command.
You can modify the core cell choices for the local nPartition or any remote nPartition in the
server complex.
Use the following command: parmodify -p# -r# -r#...
Specify the nPartition number (-p#) and the cell ID (-r#) for all cells you wish to designate
as core cell choices.
# parmodify -p0 -r2 -r0
Command succeeded.
#
The order in which you list the cells is the order in which the nPartition core cell choices are
established; the first cell listed is the first preferred core cell (choice 1), and the subsequent
cells are lower-priority core cell choices (choices 2 through 4, if specified).

Re: Enable Disks from other cell board

The SCSI controller for these disks is on the second MP board and I guess you don't have it.

Please post

# ioscan -fn

to check, but I'm quite sure after reading your parstatus.

Hope this helps!

Torsten.

Re: Enable Disks from other cell board

Thanks A Lot Steve & Torsten,

The answer was a combination of both.

Installed MP Card and Ran parmodify command and all is good.

Good Job Guys...
