Vincent,

Following is the procedure I had noted from some previous thread, which I can get hold of right now, but the info is as below.
Will post thr link to thread if I find it.



1. ioscan -H path### (eg 0/4/0/0 do not use .) # put disk as claimed from no-hw
2. ioscan -funC disk|more # check to see hw is claimed
3. mv /etc/lvmtab /etc/lvmtab.old # pvcreate fails if disk is in lvmtab
4. pvcreate -f -B /dev/rdsk/c_t_d0 # sets aside a boot area
5. mv /etc/lvmtab.old /etc/lvmtab # moves it back
6. vgcfgrestore -n vg00 /dev/rdsk/c_t_d0 # restores headers on drive
7. vgchange -a y /dev/vg00 # puts drive online
8. vgsync vg00 # if disk does not automatically start syncing (if stale)
9. mkboot /dev/rdsk/c_t_d0 # puts the boot sector in the boot area
10. mkboot -a "hpux -lq" /dev/rdsk/c_t_d0 # puts HPUX in the auto file
11. lvlnboot -Rv /dev/vg00 # updates the LIF with the info from the BDRA
12. cd /usr/sbin/diag/lif
13. mkboot -b updatediaglif -p ISL -p HPUX -p LABEL -p AUTO /dev/rdsk/c_t_d0 # to put ODE, etc. back on boot area
14. vgdisplay -v vg00 # to check it

Shalom Vincent,

Usually lvsync does the job, logical volume by logical volume.

If it fails there is something wrong preventing it from working, most likely a flakey disk or connection/cabel whatnot.

if it is root disk then follow this procedure
pvcreate -B /dev/dsk/rdsk/c#t#d#
vgcfgrestore -n /dev/vgname /dev/dsk/c#t#d#
vgchange -a y /dev/vgname
mkboot /dev/rdsk/c#t#d#
mkboot -a "hpux -lq(;0)/stand/vmunix" /dev/rdsk/c#t#d#
lvlnboot -R
vgsync /dev/vgname
else
pvcreate /dev/dsk/rdsk/c#t#d#
vgcfgrestore -n /dev/vgname /dev/dsk/c#t#d#
vgchange -a y /dev/vgname
vgsync /dev/vgname
Pls see the attached doc for details on LVM.
Cheers,

hi vincent,

procedure is differnt for itanium servers, more steps before resyncing disk is required

Follow these steps
in attached doc

Andy

[ANITH PRABHAKAR .C]

insert the disk
#ioscan -funC disk
this is to verify that the new disk is functioning
#pvcreate -f -B /dev/rdsk/cxdxtx Create the PV with 2912KB lif area
#lvextend -m 1 /dev/vg00/lvolxx /dev/dsk/cxtxdx & mirror the LVs in the vg00 to the replaced disk
#mkboot -b /dev/rdsk/cxdxtx
#mkboot -a hpux /dev/rdsk/cxtxdx
#lvlnboot -R /dev/vg00
or else u can reffer the white paper named "when good disks go bad " in the www.itrc.hp.com site

[Torsten.]

Don't do the pvcreate command.

Read the document posted by Andrew - this is the correct procedure, because this is an Integrity Server.

Good luck!
