Hi,
Normal lvextend command is not recomended,because the /stand, swap and / partitions must be contiguous.
So use advanced optiones in ignite restore.
Refer the below thread.

Hi Nirukshitha,

Only option to root partition extend is to take ignite install with Advance option.

Please refer below thread.

Hi Vishnu,

==> Only option to root partition extend is to take ignite install with Advance option.

This is nonsense. I would give you more than 3 methods to do it without Ignite.


Shehan =

Ignite is one of the method which is easy, but downtime required.

There are some other methods, but all other will require an extra disk and need proper planning.

Please let me us know if you dont have Ignite configured and if you are not willing to opt Ignite.

1.using DRD, white paper is available.
2. you can use pvmove.
3. using mirroring.
4. using lvm maintenance mode = required down time

Hi All

I already seen some argument about this in few forums regarding. But I could not figure out extract way to do this without hassle.

I have already done this for hp-ux v1 using ignite, but It is required downtime and also tape drive for backup.

Currently, I don't have tape drive as well as getting the downtime is also bit difficult.

Hence, I would like to know whether we can proceed this in the new hp-ux version using another good method as mentioned.

Hi Shehan,

Extending root fs in hpux can be done without restoring ignite backup.but you required folloing things,

1. root disk must be mirrored.(lvm mirroring)
2.online JFS should be installed.

(swap, root(/) fs are contiguous)
how to perform.

1.do lvreduce to reduce mirror volume in mirrored disk until root volume.
lvreduce -m 0 /dev/vg00/lvol8 /dev/dsk/cxtxtx (this should mirrored disk)

do this until root disk.(don't reduce for root fs in mirrored disk)

2.reduce root fs in root disk(make sure root fs mirrored and syncd)

3. extend root fs in mirrored disk.

4.Remirror all fs as usual.

5.now all fs mirrored and syncd(wait for syncing)

6.now reduce mirror for all other volume after root fs from root disk.(after sync only you should do)

7.once reduced. remirror again. hopefully this method wll help you.we don't need downtime for this method..only steps need to followed properly.

[Kanagaraj]

Small correction on above post.
do this until root volume(lvol3).(don't reduce for root fs in mirrored disk)

[Kanagaraj]

step 2:2.reduce root fs in root disk(make sure root fs mirrored and syncd)

this may confuse you,,,

reduce mirror of root volume(/) from root disk

Hello Kanagaraj,

Can you explain point no: 6 & 7 in detail and again why we are reducing...
