Disk mirror in HPUX 11.11

[GB Tek]

I want to mirror our system but did not see a way to do it in SAM. Is there a link to mirroring using the command line or using SAM to mirror the root drive?

[S.K. Chan]

Can't do that with SAM. This is the process I used (you got to have Mirror/UX installed) or you can take a look at Chapter16 (LVM) of the Software Recovery Handbook.

Mirroring Process
-----------------
o Assuming c1t2d0 is primary disk and c2t2d0 is the disk to be mirrored.
o Assuming (lvol1=/stand;lvol2=primary swap;lvol3=2ndary swap;lvol4=/;lvol5=/opt)

# swlist -l bundle| grep -i mirror
=> Make sure you have MirrorUX installed
# pvcreate -f -B /dev/rdsk/c2t2d0
# mkboot -l /dev/rdsk/c2t2d0
=> Create boot track (place boot utilities in boot area), -l means treat device as LVM disk.
# mkboot -a "hpux -lq" /dev/rdsk/c2t2d0
=> Add AUTO file in boot LIF area, "lq" option is to bypass quorum check.
=> Repeat for primary disk (c1t2d0) as well.
# lifcp /dev/rdsk/c2t2d0:AUTO -
=> Check content of AUTO file. Repeat for primary disk (c1t2d0).
# vgextend /dev/vg00 /dev/dsk/c2t2d0
=> Adding disk to root VG.
# pvdisplay -v /dev/dsk/c2t2d0
=> Note of the order of LVs (assuming it's lvol1,lvol2,lvol3,lvol4 & lvol5)
# lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t2d0
=> Repeat for lvol2->lvol5
# lvlnboot -r /dev/vg00/lvol4 /dev/vg00
# lvlnboot -b /dev/vg00/lvol1 /dev/vg00
# lvlnboot -s /dev/vg00/lvol2 /dev/vg00
# lvlnboot -d /dev/vg00/lvol2 /dev/vg00
=> Update BDRA (root, boot, swap and dump)
# lvlnboot -v
=> Check to make sure both disks are listed for root, boot and swap definition.
# setboot
=> Display boot path.
# setboot -a 0/0/2/0.2.0
=> Change alternate boot path to mirrored disk.
# shutdown -r -y 0
=> Interrupt upon bootup and select alt path to boot from in order to test.

Installing ODE (Offline Diagnostics)
------------------------------------
# ll /usr/sbin/diag/lif/updatediaglif
=> Make sure the file exist.
# lifls -l /dev/rdsk/c2t2d0
=> List content of LIF dir (should have ISL,AUTO,HPUX,PAD,LABEL).
# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c2t2d0
=> Install ODE LIF files while "protecting" the existing LIF files.
=> Use updatediaglif2 for 11.0 64-bit.
# lifls -l /dev/rdsk/c2t2d0
=> Should now see the additional LIF files.

If your primary boot disk has the ODE LIF files you have got to go through the ODE installation for your mirrorred disk as well.

Hi

here it goes

Create the physical volume of the new disk
# pvcreate -f -B /dev/rdsk/cXtYdZ -> disk where you want to put the mirror in

Create a bootable space on the disk
# mkboot -l /dev/rdsk/cXtYdZ

# mkboot -a "hpux (;0)/stand/vmunix" /dev/rdsk/cXtYdZ

Extend vg00 into the new disk
# vgextend /dev/vg00 /dev/dsk/cXtYdZ

Create the mirrors of the lvolumes
#lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/cXtYdZ

#lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/cXtYdZ

#lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/cXtYdZ

and the remaining lvolumes (these 3 ones must be in this order)

Put it as a bootable disk

#lvlnboot -b /dev/vg00/lvol1 -> boot

#lvlnboot -s /dev/vg00/lvol2 -> swap

#lvlnboot -r /dev/vg00/lvol3 -> root

#lvlnboot -R

Verify everything is ok

# lvlnboot -v

And save config of vg00

# vgcfgbackup vg00




Bye

Is Mirror-UX part of the install cd set? I loaded all apps but don't see it loaded when I run the swlist ... command.

[S.K. Chan · Accepted solution]

It's not. MirrorUX is a licensed software. You'll have to purchase it and then apply for the codeword to unlock it from the apps CD. If you have it installed it should show something like this.
# swlist -l bundle|grep -i mirror
B2491BA B.11.00 MirrorDisk/UX
