VxVM v3.5, Unencapsulation & no rootdg

[s2budd]

Hello

I would appreciate some help please.

Using VxVM & VxFS v3.5 on Solaris 9.
The root disks were encapsulated with two extra volumes on non root disks.
There are two data volumes within the cdrdg disk group.
I have unencapsulated the root disk and re-booted with the view to:
1. install Disksuite/SVM
2. Deport the data diskgroup located on data disks
3. Remove Veritas VxVM & VxFS v3.5
4. Install Veritas VxVM & VxFS v4.1
5. Import the data diskgroup.

However, on booting after unencapsulating the root disks I get the following errors:

Starting VxVM restore daemon...
VxVM starting in boot mode...
Sep 5 08:37:28 vxvm:vxconfigd: enable failed: Error in disk group configuration copies
Sep 5 08:37:28 vxvm:vxconfigd: No valid disk found containing disk group; transactions are disabled.
Sep 5 08:37:28 vxvm:vxconfigd: Rootdg cannot be imported during boot
VxVM general startup...
vxvm:vxconfigd: ERROR: enable failed: Error in disk group configuration copies
No valid disk found containing disk group; transactions are disabled.
vxvm: Vold is not enabled for transactions
No volumes started

vxvm:vxrecover: ERROR: IPC failure: Configuration daemon is not accessible
Starting VxVM Diskgroup Configuration Log Daemon...

I think that this is due to there now not being a rootdg disk group.

The contents of /etc/vfstab are:

fd - /dev/fd fd - no -
/proc - /proc proc - no -
#/dev/dsk/c1t0d0s1 - - swap - no -
/dev/md/dsk/d1 - - swap - no -
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no logging
/dev/md/dsk/d3 /dev/md/rdsk/d3 /var ufs 1 no logging
swap - /tmp tmpfs - yes size=512m
#/dev/vx/dsk/cdrdg/cdrt01vol /dev/vx/rdsk/cdrdg/cdrt01vol /cdrt vxfs 1 yes log
#/dev/vx/dsk/cdrdg/cdrc01vol /dev/vx/rdsk/cdrdg/cdrc01vol /cdrc vxfs 1 yes log

Does anyone have any idea what I can do?
I have removed the two Veritas file systems out of /etc/vfstab and the system boots OK but
I can nolonger mount the Veritas volumes.

I have now added DiskSuite/SVM to the root disks and mirrored.
I have not touched the slices 3 & 4, just added a slice 7 from unused disk space.

Should I add the DiskSuite root disks to rootdg, mount the veritas file systems, deport them,
remove Veritas v3.5 and then install V4.1 and import the disk group.
or
just continue with the removal of v3.5 and import the disk group when v4.1 is installed.

Many thanks

I think a rootdg was required by Veritas Volume Manager until version 4.0, so the upgrade may be a good plan; I'd check with Veritas first though to be sure.

Alternatively if there's a spare disk you can create an (empty) rootdg on then that might be an option. I think you don't even need to use a whole disk, but that might be fiddly.
