Need to replace the faulty disk in hpux 11.2 [Itanium server]
I need to replace the faulty root disk in hpux 11.23 server [Itanium]
Do I need to partition the disk ?
or just to do the vgcfgrestore?
Could you have any planned steps?

> Torsten: Same document, but JRF sent the new link
And there's another example of how we have lost information (even if only meta) when the docs.hp.com transitioned to the "new and improved" format!

Re: Need to replace the faulty disk in hpux 11.2 [Itanium server]
c01911837.pdf
is somehow meaningless compared to
When_Good_Disks_Go_Bad_WP.pdf
(I still cannot understand why docs.hp.com must die.)
Hope this helps!

Torsten.

Re: Need to replace the faulty disk in hpux 11.2 [Itanium server]
Thanks for your reply.
But that doc is for 11.3
Mine is 11.23
the confusing thing ia that Iam not sure whether I need to do the [efi]partitioning in the new disk [which is to be replaced ].
Few doc is telling the partitioning is needed then only need to do vgcfgrestore.
But few telling no need.
Finally I prepared few steps my self by referring few docs.
1. Login to the server as root
2. Take backup of configuration files.
cp -p /etc/lvmtab /etc/lvmtab.20100609.SKR
cp -p /etc/lvmconf/vglocal.conf /etc/lvmconf/vglocal.conf.20100609.SKR
vgdisplay -v
3. Detach the PV from LVM
4. Halt LVM access to the disk.
pvchange -a N /dev/dsk/ctds2
replace the faulty disk
6. Scan the new disk and check the status of the disk
7.# ioscan -fnC disk
8. Create the device files for the newly added disk
# insf -eC disk
9. # vi /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB
10. idisk -wf /tmp/partitionfile /dev/rdsk/cxtydz
11. pvcreate -fB /dev/rdsk/cxtydzs2 [s2 is imp]
12. insf -e
13. mkboot -e -l /dev/dsk/cxtydz [ctd only]
14. Restore VG configuration in to the new disk
vgcfgrestore -n /dev/vg00 /dev/rdsk/CTD [CTD only]
13. update lvol boot paths
# lvlnboot -r /dev/vg00/lvol3 /dev/vg00
# lvlnboot -b /dev/vg00/lvol1 /dev/vg00
# lvlnboot -s /dev/vg00/lvol2 /dev/vg00
# lvlnboot -d /dev/vg00/lvol2 /dev/vg00
14. Use efi_ls to confirm that the EFI partition is present and populated on the
new disk:
# efi_ls -d /dev/rdsk/cxtydzs1 ====> [S1 is important]
15. edit the AUTO file so we can boot when one disk is missing.
# efi_cp -d /dev/rdsk/c2t0d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO -------------may confuse here AUTO is in EFI so we are using s1
# vi /tmp/AUTO
modify "boot vmunix" to "boot vmunix -lq"
then put back the file on[ both ]EFI partitions with: mean in both disks
# efi_cp -d /dev/rdsk/c2t1d0s1 /tmp/AUTO /EFI/HPUX/AUTO [ imagine /EFI/HPUX/AUTO is part of s1]
# efi_cp -d /dev/rdsk/c2t0d0s1 /tmp/AUTO /EFI/HPUX/AUTO
16. set the alternate EFI Bootpath to the mirrored disk
17. setboot -a HW-path to the mirrored disk
18. that s it!!!???
pls advice!!!! thanks inadvance

Re: Need to replace the faulty disk in hpux 11.2 [Itanium server]
So use the document!
Your procedure looks good.
Do you have SAS disks?
In this case the procedure may be even a bit different.
Hope this helps!

Torsten.
