new disk installation

Had HP tech install 6 18 gig drives into existing disk array that already had 10 existing 4 gig drives. Drives have the fault light on. Tech mentioned that we would need to init the drives?? We cannot see the drives in SAM or with ioscan.
System: K560 OS:11.0 unix

What needs to be done??

Re: new disk installation

What kind of disk array?

Re: new disk installation

What type of array? Smart enclosure, Autoraid, ...? There are different answers for different arrays.

Autoraid:
Previously Used
disk was used by another autoraid, "include" manually either through the panel or: arraycfg -D A2 {or whatever disk slot} -a 00000F23423 {or whatever serial number}


Smart Enclosure:
The system will need to be rebooted, then you should be able to see them with ioscan.
III) How to add a disk to a Volume Group
Note The following examples is using the disk c1t6d0 and the volume
group vg01

1) Prepare the disk
pvcreate /dev/rdsk/c1t6d0

Note if the disk was previously used in another VG use the
following command instead:

pvcreate -f /dev/rdsk/c1t6d0

Note: Use caution when using pvcreate -f as this will
overwrite the existing volume group information on the disk.

2) Add the disk to the Volume Group
vgextend /dev/vg01 /dev/dsk/c1t6d0

Hope this helps.

Re: new disk installation

The array is autoraid.

Re: new disk installation

Hi Mark,

you have to use the gridmanger to add those disk as part of a lun.

Look at the user guide in the above link.

Hope this helps.

Re: new disk installation

The autoraid instructions I posted earlier are ones that I know will work for a 12H. Don't know about a 20 having never worked on one of those.

Re: new disk installation

Mark, a model 20 array is not the same as an autoraid.
These are differnet products and are handled differently.
What needs to be done is the new iscs need to be configured into te array using either gridmanager for a Nike Model 20, or arraymgr (I think) for an autoraid.
Only once this has been done, will the array "present" the discs to the outside world, and thus have them seen by ioscan and SAM.
The HP enginer should have been able to assist you with this.

Re: new disk installation

gridmanager shows the new drives as removed. The fault light is on for all these drives. Does the disk array need to be power cycled?
Not sure what the next step is?

Re: new disk installation

Hi Mark,

Suggest you power down the array. Then restart the Disk Array and run the grid manager. If the disk led's are still yellow,You may need disks to be replaced. Also check and see if the firmware on the disk array controller can support the disks you have installed on the system.

Hope this helps.

Re: new disk installation

When we power cycle the array, should we expect the fault lights to go off before we do any gridmanager config.

Re: new disk installation

Hello,

Check that the PROM revision is 8.02 if you have the Sauna SP. If you have the Phoenix SP, the PROM revision should be 1.73 in order to recognise the disks.

PROM revision can be seen in the Presentation menu under Gridmanager on the upper left corner of your screen.

Re: new disk installation

Hi Mark,

Yes the disk yellow led's should go off before you attempt to use those disk. Yellow led indication on the disk is an indication of a fulty disk. Once you power on the array, wait for a couple of minutes for the array to boot and come to ready state. If you have a serial cable connected to the serial port on the array, you should be able to see the bootup messages.

Hope this helps.

Re: new disk installation

This is a critical production system. Can I remove and reseat the disks without affecting the system in an attempt to correct this problem?

Re: new disk installation

From gridmanager the prom is 1.63. Will this cause the led fault light to be on for these 18 gig disks.

Re: new disk installation

Hello,

I think that if the firmware version is lower than it should, the disk array would not recognise the disks and would think that the disks are faulty.

You need PROM version 1.73 or higher to be able to recognise the 18Gb disks.

Call your HP tech and tell him to upgrade the firmware of the SPs to Revision 9.55.01 (corresponding PROM is 1.73).

HTH,
