Extend / mount point (only 1 disk)
I have checked some posts but I didn't find the one adapted to my case...
I have a RP3440 with only 1 disk.
I would like to extend the / mount point (lvol3, vg00).
I thought I could do it using ILO (Management Processor) but the fact is that disk management is not available at this step.
It has to be done before booting the system (as for Linux system when you boot from a CD and use tool like fdisk) but I don't know how to complete this action on a HP-UX system.
Could you please help me.
Regards
Eric

Re: Extend / mount point (only 1 disk)
1.Take Ignite backup on tape or on to Ignite
2. Boot the system either by boot helper or tape
3. Change settings during recovery process.

Re: Extend / mount point (only 1 disk)
Only way is to Reignite your system. Or there is an unsupported way to extend (I read in this forum)
1. Find out the next logical volume to your root file system. Say lvol4.
2. Reduce the mirrors on lvol4.
lvreduce -m 0 /dev/vg00/lvol4 /dev/dsk/cxtydz
where cxtydz is the primary disk. This will free up space after lvol3, your root logical volume.
3. Now you can extend root as it has the contiguous space available.
lvextend -L new_size_in_mb /dev/vg00/lvol3
fsadm -b
This should extend the filesystem.
4. Extend the mirror back to primary on lvol4.
lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/cxtydz
You may have to turn-off "strict" on lvol4 if it gives you any error.
If you don't have onlineJFS or if you have any doubts, use make_tape_reocvery process.

Re: Extend / mount point (only 1 disk)
In fact, I'd like to install ignite and / is too small...
That's why I would like to extend the / mount point.

Re: Extend / mount point (only 1 disk)
(By the way, when you do a lvreduce, it does not reduce the lvol4 space at the end, isn't it?
If the space was reduced at the beginning of lvol4, I could lvextend lvol3 but I think it is not the case unfortunately...)

Re: Extend / mount point (only 1 disk)
Even if you free up lvol4, you won't be able to know whether they freed up at the beginning or at the end.
You have to use Ignite recovery option.

It won't work even if you turn off "strict" after reducing mirror. Not only on / , it won't even work on any other logical volume which was mirrored and strict when it was created. Tested two days back and couldn't do it other than igniting it.

Re: Extend / mount point (only 1 disk)
use swinstall --> select source
then go to actions ---> change target and chose directory wherever you have enough space.

Re: Extend / mount point (only 1 disk)
with Online JFS, and 2 disks you could extend it.
you can pvmove each lvol over to the other disk. when you get to lvol3 you can then extend lvol 3 on the new disk as it will be contiguous, then continue with your pvmoves of the rest of the lvols.
I have done this many times.
But you stated you have 1 disk so you have no option but to rebuild.
