Disk array

[farhi]

A customer has just purchased a fully loaded HP AutoRaid array. He is upset because when the first time to access the disk array, he can see only 2 Go.

Help.

Hi,

have a look with arraydsp:
arraydsp -i # to get array-id
arraydsp -a
to see the config of the autoraid (especially the LUNs)

Hi,

On system startup it takes some time to initialize the array manager daemon ( ARM60srvr).

Ensure that you have the correct patch loaded for the disk array. In HP-UX 11.0 it normally comes in the Hardware critical patch bundle.

In the absence of a correct patch it shows funny behavior.

Regards,

Pramod

Can you see the controller, disks, etc... with SAM? Noughty sam :-)

I bet you that some of the disks are not
included. ie AutoInclude is off.
It is probably a good idea to switch it off
since you insert new disks during working hours
and you don't want a data migration to take
up all controller cpu.

However 2G is real low, i didn't think you
could get an autoraid disk less than 36G now!
Try to format the array using the
control pannel in controller area. After
this verify that all the disks are in an
included state.

arraydsp -i
to get the serial number
arraydsp -d
to get the disk states.

Remember too that the firmware revision
of the controllers may not support certain
disk capacities. You may need to upgrade
controller firmware using
the /opt/hparray/bin/download command
See what revision you got with
arraydsp -c

Also not that after creating LUNs on the
autoraid, they will not be seen on the host
until you reset the sdisk driver,
ioscan -fn
Then insf to get your special files.
