Resynch primary and mirror disks.

[Annelise Wilken]

I have an rx4640 Integrity server with 2 external disks as follows:

c4t0d0 - primary root disk
c4t1d0 - root mirror copy

To test that I could boot from the mirror disk I did the following:
1. shutdown server.
2. pulled out primary disk
3. Started server up and chose the ALT disk from EFI boot menu.
4. Server booted correctly.
5. Shut server down - inserted primary disk
6. Booted server from primary disk
7. server booted correctly - BUT when I do vgdisplay -v vg00

my logical volumes are not sync and looking at the logical volumes (lvdisplay -v /dev/vg00/lvol9 etc....) they are stale - how do I resynch my primary (c4t0d0) with the mirror (c4t1d0)copy?

Thanks

vgsync vg00 should do the trick..

Hi Annelise,

You can use:

vgsync /dev/vg00

for whole volume group synchronisation or

lvsync /dev/vg00/lvol9

for particular logical volume.
