Normally you'd remove the disk from VxVM before you physically remove
it.
How can I chase out the reference to the

Hi,
for maintenance purpose for our Sun Server we have created a Solaris
WANBOOT Image with VxVM 5.0 MP1 included.
The plan for using this WANBOOT Image is as follow:
- boot the Sun machine from the network using this WANBOOT image
- import the rootdg from the local disks
- do what ever
Has anyone used more then just 2 disks to mirror rootdg?
Because I have to do some odd migration stuff, I want to have 3 rootdisks.
rootdisk, rootmirror, and rootraidmirror.
Just wondering if rootdg should only be mirrored by 2 disks, or if more then
that is OK.

Not sure if this is a good idea when you want to do maintenance on a
Production box.
Consider this in your design to solve whatever issue you have:
1. Make 1 local disk available, keep it out of control of Veritas.
(altboot)
2. Create all the slices on altboot similar in size as the Root disk

in VxFS, you can use the 'checkpoint' capability to do exactly

That's appropriate if you're changing out a platter but want to retain

Snapshots are read-only.
VxFS offers ways using checkpoints (look at fsckptadm and
fsckpt_restore) to snapshot a file system and do a complete restore of
an entire file system. VxVM offers similar functionality using
various techniques, including various operations within the 'vxsnap'
command.
