Hi,

What kind of external storage device do you have? I also see only one internal HD

I suppose your server is an rx..

[Arunvijai_4]

I hope, you have only one internal HDD connected to your server? I hope, you ran # ioscan -fnC disk

Hi Michael,

Depending on just what model this server is & which SCSI HBA the disk is attached to, it's possible that the way the system is configured the main partition can't see it.
It may be that you need another MP card or you may need to partition the system such that the HBA is now included. But either way we need more info from you to help. Need model, # of MP boards, etc.

Rgds,
Jeff

Hi Michael,

I guess the reason is here:

0/2/1/0/4/0 unknown PCI-X RAID (0e110046)

There is no driver for the RAID card.
You need to install the driver from the app CD.

Hi


Depending on the card type you find the software here

hi, Thanks for previous responses my system is
working now to certain extend.
I have created a mirroring disk in case of immergency. When I try to boot in in the secondary disk it gives the error,

booting disk is not found, press any key to continue.

The print out of logical volume boot is as follows:

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t2d0s2 (0/0/2/0.2.0) -- Boot Disk
/dev/dsk/c0t0d0 (0/0/2/0.0.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t2d0s2
/dev/dsk/c0t0d0
Root: lvol3 on: /dev/dsk/c0t2d0s2
/dev/dsk/c0t0d0
Swap: lvol2 on: /dev/dsk/c0t2d0s2
/dev/dsk/c0t0d0
Dump: lvol2 on: /dev/dsk/c0t2d0s2, 0


Can Any one assist on this?

Regards,

Michael

Am I correct that you have 11.23 on an Itanium server? There are some new procedures for setting up mirroring on Itanium (Integrity) servers since its root disk is partitioned. Search the forums and you will find the answer as it has been posted before.

Seems to be a good link (to another link).

[Torsten.]

This is a part from your output:

/dev/dsk/c0t2d0s2 (0/0/2/0.2.0) -- Boot Disk
/dev/dsk/c0t0d0 (0/0/2/0.0.0) -- Boot Disk

You can see, there is a device "c0t2d0s2" and a "c0t0d0". First one is working, first one has *partitions". You will see 3 different partitions for this disk in ioscan:

c0t2d0s1 - EFI Boot partition
c0t2d0s2 - OS
c0t2d0s3 - system utilities

Your second disk has only 1 "partition" for OS, boot area is missing! So this disk cannot boot!

You need to follow the given procedure (see link above) to mirror a boot disk in itanium servers, create disk partitions (idisk) and so on...
always use the ...s2 device for LVM related commands!
