Re: which come first

If you have mirrordisk installed already, you don't need to worry about online JFS to mirror your volumes.

Online JFS in a nutshell lets you make filesystem changes on the fly (such as resizing filesystems, changing filesystem options etc...)

They're independant packages and one doesn't need the other to work.

Having said that though, it's nice to have both because you don't need to unmount a filesystem to increase the size if you have online JFS.

Re: which come first

Hi,

It doesn't matter which order. I am sure that
if you are installing OnLineJFS it will ask
for the system to be rebooted after the
software has been installed.

To mirror your vg00, here is an easy example.

# pvcreate -B /dev/rdsk/cxtydz
# vgextend /dev/vg00 /dev/dsk/cxtydz
# mkboot /dev/rdsk/cxtydz
# mkboot -a "hpux -lq(;0) /stand/vmunix" /dev/rdsk/cxtydz
# lvlnboot -R
# for LVOL in /dev/vg00/lv*
> do
> echo $LVOL
> lvextend -m 1 $LVOL
> done
# lvlnboot -v

Online JFS is for having the ability to extend filesystems seamlessly to the user community, very helpful in avoiding downtime for users.

MirrorDisk/UX is your mirroring product for all filesystems.

Also I have attached a document detailing the process we use to mirror root volume groups, we take a few extra precautions since we are in a high pressure environment here. Hope this helps.

Good Luck
