Re: how to resync a harddisk
I would investigate the reason why the disk disappeared. Look at your /var/adm/syslog/OLDsyslog.log and look for any disk errors.
If you find it ok, then doing a vgsync will synchronize the disks. First look for a "vgsync" process
ps -ef|grep vgsync
If you find anything running, then leave it running and it will take care of it. Otherwise run
vgsync vg00

Re: how to resync a harddisk
If the output is similar to this then you need to run the 'vgsync' command.
# lvdisplay -v /dev/vg01/lvol4
--- Logical volumes ---
LV Name /dev/vg01/lvol4
VG Name /dev/vg01
LV Permission read/write
LV Status available/stale
# vgsync /dev/vg01
Have a look at the man page for 'vgsync'
Regards
Michael

Re: how to resync a harddisk
If you want to mirror the data back to the disk which was not available previously do the following
You can use vgsync command to resync mirror disks. Make sure that the vgsyc is not running.
and the disk is available and OK, use diskinfo -v command to check the disk.
