To see which hardwarepath is connected to which scsi address (and to see if Unix has CLAIMED the device, that is loaded a driver for it):
[ELITIL] ELITIL2: / # ioscan -fnC disk

 

You can dd to verify which physical disk is which,i.e.
[ELITIL] ELITIL2: / # dd if=/dev/dsk/c3t0d0 of=/dev/null bs=1024
will hit the good disk (in this case), just check the disk and see if the light is on steady.

Now I made a mistake and executed these commands to soon. That made tme think the disk was a DOA (DeadOnArrival). Seemed that I used a PA-RISC procedere and this one differs from Itanium.
Create a physical volume using pvcreate with the -B option. Be sure to use the device file denoting the HP-UX partition.
[ELITIL] ELITIL2: / #   pvcreate -B -f /dev/rdsk/c3t0d0s2

pvcreate: Couldn’t open physical volume “/dev/rdsk/c3t0d0s2”:

The next commands were executed to check if the disk was really a DOA or if it was alive. And it was alive:

Enter the insf command with the -e option to create the legacy device files for all the partitions:
# insf -e -H 0/1/1/1.0.0
You now have the following device files for this disk:
/dev/dsk/c3t0d0

The Service partition (block access)
/dev/rdsk/c3t0d0s3
The Service partition (character access)
Starting with the HP-UX 11i v3 release, you must have the persistent device special files. To achieve this, use the insf command with the –e option or -eC disk option. If you are running insf –e –H <hw_path>, you must run the insf command for both the legacy and new style lun hardware path. For example:
# insf -e -H 0/5/1/0.5.14.0.0.0.1 50
You now have the following device files for this disk:
/dev/disk/disk75
The entire disk (block access)
/dev/rdisk/disk75
The entire disk (character access)
/dev/disk/disk75_p1
The EFI partition (block access)
/dev/rdisk/disk75_p1
The EFI partition (character access)
/dev/disk/disk75_p2
The HP-UX partition (block access)
/dev/rdisk/disk75_p2
The HP-UX partition (character access)
/dev/disk/disk75_p3
The Service partition (block access)
/dev/rdisk/disk75_p3
The Service partition (character access)

If needed update the autoboot file on the EFI partition:
[ELITIL] ELITIL2: /tmp #  efi_cp -d /dev/rdsk/c3t0d0s1 -u /EFI/HPUX/AUTO /tmp/auto-alt

If you expect to boot from this disk only when you have lost quorum, you can use the string “boot vmunix –lq” to disable quorum checking (This not recommended; use this with caution to prevent data loss). Otherwise use just the default “boot vmunix” option. I use the -lq parameters so I don’t have to manualy select the boot drive after a rebbot when the master-boot-disk has failed.

[ELITIL] ELITIL2: /tmp # cat auto-alt
boot vmunix -lq
~
~
“auto-alt” 1 line, 16 characters

Check the config of the other disk:
[ELITIL] ELITIL2: /tmp #  efi_cp -d /dev/rdsk/c2t1d0s1 -u /EFI/HPUX/AUTO /tmp/auto-alt_2

[ELITIL] ELITIL2: /tmp # cat auto-alt
boot vmunix -lq
~
~
“auto-alt” 1 line, 16 characters

All files are what I want them to be so I don’t have to change them. If NOT OK then adjust the files and copy them back with the following commands:[ELITIL] ELITIL2: /tmp #  efi_cp -d /dev/rdsk/c3t0d0s1 /tmp/auto-alt /EFI/HPUX/AUTO
[ELITIL] ELITIL2: /tmp #  efi_cp -d /dev/rdsk/c2t1d0s1
/tmp/auto-alt_2 /EFI/HPUX/AUTO

 

Use the lvextend command to mirror each logical volume in vg00 (the root volume group) onto the specified physical  volume. You must extend the logical volumes in the same order that they are configured on the original boot disk. Use the pvdisplay command with the -v option to determine the list of logical volumes and their order.

[ELITIL] ELITIL2: /tmp # pvdisplay -v /dev/dsk/c2t1d0s2|grep ‘current.*0000 $’

This was also a good idea to automate the list of commands from above:

# for lvol in lvol1 lvol2 lvol3 … (specify any LV you need to mirror)
> do
> lvextend –m 1 /dev/vgXX/$lvol /dev/dsk/cXtXdX
> done

 

Update the root volume group information:
[ELITIL] ELITIL2: /tmp # lvlnboot -R /dev/vg00
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

Verify that the mirrored disk is displayed as a boot disk and that the boot, root, and swap logical volumes appear on both disks:
[ELITIL] ELITIL2: /tmp # lvlnboot -v

Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
        /dev/dsk/c2t1d0s2 (0/1/1/0.1.0) — Boot Disk
        /dev/dsk/c3t0d0s2 (0/1/1/1.0.0) — Boot Disk
Boot: lvol1     on:     /dev/dsk/c2t1d0s2
                        /dev/dsk/c3t0d0s2
Root: lvol3     on:     /dev/dsk/c2t1d0s2
                        /dev/dsk/c3t0d0s2
Swap: lvol2     on:     /dev/dsk/c2t1d0s2
                        /dev/dsk/c3t0d0s2
Dump: lvol2     on:     /dev/dsk/c2t1d0s2, 0

Specify the mirror disk as the alternate boot path in nonvolatile memory:
[ELITIL] ELITIL2: /tmp # setboot -a 0/1/1/1.0.0

To add a line to /stand/bootconf for the new boot disk, use vi or another text editor as follows:
[ELITIL] ELITIL2: /tmp # vi /stand/bootconf

“/stand/bootconf” 2 lines, 42 characters
l  /dev/dsk/c2t1d0s2
l  /dev/dsk/c3t0d0s2
~
~

Check if everything is OK. Per logical volume you must see “LV Status available/synced” and “Used PV 2”.

Best test is to reboot hte system from the alternate boot disk. Make an Ignite backup before you do dthis.
