Mirror HP-UX root disk on Itanium rx4640 server.

[Juan Gonzalez_2]

I covered the root disk from VxVM to LVM with an Ignite tape successfully. I can boot from the primary but not from the alternate disk I mirrored. Since I already had the devices /dev/rdsk/c2t2d0s1 and
/dev/rdsk/c2t2d0s2 I did did not create a partition file and run the idisk -wf and the insf -e -C commands to create the devices.

What I did was mkboot -e -l /dev/rdsk/c2t1d0
Then I checked by doing efi_ls -d /dev/rdsk/c2t2d0s1 and lifls -l /dev/rdsk/c2t1d0s2 and they check out okay.
The out put of efi_ls -d /dev/rdsk/c2t2d0s1 is FileName Last Modified Size
EFI/ 2/ 5/2007 0
STARTUP.NSH 2/ 5/2007 296

total space 523251712 bytes, free space 519962624 bytes
and the ouput of lifls -l /dev/rdsk/c2t1d0s2 is:
volume ISL10 data size 7984 directory size 8 05/12/01 06:47:06

Then I did mkboot -a "boot vmunix" /dev/dsk/c2t1d0.
Then I checked with the command efi_cp -d /dev/dsk/c3t0d0s1 -u /EFI/HPUX/AUTO /tmp/x; cat /tmp/x.

The ouput was boot vmunix

Then ran pvcreate -B /dev/rdsk/c2t1d0s2 and vgextend vg00 /dev/dsk/c2t1d0s2 commands successfully.

Then I ran the lvextend -m 1 command for all the logical volumes in the root drive successfully.
Then I ran commands
lvlnboot -r /dev/vg00/lvol3
lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2

Then i checked by doing lvlnboot -v got this output below.
Boot Definitions for Volume Group /dev/vg00:

/dev/dsk/c3t0d0s2 (0/1/1/1.0.0) -- Boot Disk

Swap: lvol2 on: /dev/dsk/c3t0d0s2
/dev/dsk/c2t1d0s2
Dump: lvol2 on: /dev/dsk/c3t0d0s2, 0

I did setboot before doing the next step which is setboot -a and output was

Primary bootpath : 0/1/1/1.0.0
HA Alternate bootpath : 0/1/1/0.1.0
Alternate bootpath :

Autoboot is ON (enabled)

so i did not do the setboot -a.

Then I rebooted the server and got the error message below when I tried to boot off of the new mirrored drive.
Scsi (Pun1,Lun0) HP 146 GMAT3 147NC HPC2 (320 MBytes/sec)
Loading.: HP-UX HA Alternate Boot: 0/1/1/0.1.0
Load of HP-UX HA Alternate Boot: 0/1/1/0.1.0 failed: Not Found
Press any key to continue

What did I go wrong? What do I need to do to be able to boot off of the mirroredc drive?

Hi,

when EFI boots, you should see 2 entries, not only one.

(1) Scsi (Pun1,Lun0) HP 146 GMAT3 147NC HPC2 (320 MBytes/sec)


(2) Scsi(Pun0,Lun0) ...

And: if the alternate path is not set, you cannot boot from it.

Do you have external devices connected to the core I/O card?

[Juan Gonzalez_2]

I do see two entries on the EFI boot menu and I choose the second entry to boot from which fails. I do not have an externel disk drives yet. I do have a SCSI tape drive which I also modified the EFI boot menu to add the Tape drive.

[Torsten.]

You must not connect *any* device to the external core connectors!

If you see 2 disk entries, inspect and explore the disks from the EFI level, like

fs0> dir

and

fs1> dir

to find the hpux OS loader.

[Juan Gonzalez_2]

Torsten I went into the EFI shell and checked the files in each of the disk and they have the same amount of files and size. Any other clues to look for?
