Solaris vxvm unencapsulate rootdisk

If your system partitions (/, swap, /usr, /var) are located on more than one physical disk, you will have to manually "unencapsulate" your root disk instead of using Veritas' vxunroot command below.

1. Modify /etc/vfstab to reference the cxtxdxsx devices instead of the VxVM devices. There should be a file vfstab.prevm, use this one if it is there

2. Comment out the lines in /etc/system between:

* vxvm_START (do not remove)
* vxvm_END (do not remove)

3. Run the following command to prevent VxVM from starting up after reboot:

touch /etc/vx/reconfig.d/state.d/install-db

4. Reboot the system. After the reboot, you may uninstall VxVM if needed.


System partitions on boot disk
The Veritas vxunroot command is used to unencapsulate a root disk that contains all your system partitions. However, if the root disk is mirrored, you have to remove the mirror plexes.

Example:

# /etc/vx/bin/vxunroot

This operation will convert the following file systems from
volumes to regular partitions: root swap usr var opt home

ERROR: There are 2 plexes associated with volume rootvol
The vxunroot operation cannot proceed.

Listing of all volumes in rootdg:

# vxprint -v -g rootdg
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
v opt gen ENABLED 4198392 - ACTIVE - -

v swapvol swap ENABLED 4198392 - ACTIVE - -
v usr gen ENABLED 4198392 - ACTIVE - -
v var gen ENABLED 4198392 - ACTIVE - -

Here we see that rootdg contains volumes opt, rootvol, swapvol, usr, and var. Let's see if the volumes consist of more than one plex.

# vxprint opt rootvol swapvol usr var

VM disk rootdisk-mirror contains mirror plexes for volumes opt,rootvol, swapvol, usr, and var. We have to remove the plexes before proceeding with vxunroot.

# vxplex -o rm dis opt-02 rootvol-02 swapvol-02 usr-02 var-02

# /etc/vx/bin/vxunroot

This operation will convert the following file systems from
volumes to regular partitions: root swap usr var opt home

Replace volume rootvol with c0t0d0s0.

This operation will require a system reboot. If you choose to
continue with this operation, system configuration will be updated
to discontinue use of the volume manager for your root and swap
devices.

Do you wish to do this now [y,n,q,?] (default: y)

After a reboot, the root disk will be unencapsulated.

Solaris printer administration

Configuring Print Clients
There are a couple of utilities you can use to create print clients:

Admintool -- to be used for Solaris 2.6 and Solaris 7
The printmgr utility in Solaris 8 (in /usr/sadm/admin/bin)
However, they both execute the same commands:

# lpadmin -p banana -s server!remote-queue
Note that:
# enable banana
# accept banana
banana is the queue you are creating to print to on the client.
server is the machine you are sending the print job to.
remote-queue is the name of the print queue on the machine you are sending the print job to.
If the remote-queue is the same as the queue you are creating on the client then you won't need the !remote-queue part of the command.

Solaris Vxvm vxdiskadm option 4 replacing failed rootdisk fail

Exact Error Message
"vxvm:vxdg: ERROR: associating disk-media rootdisk with c0t0d0s2: Disk public region is too small"

Details:
Sometimes the above vxdiskadm command will fail. If it does, try to ensure that the disk is replaced with a disk with the same geometry. Use the output from the format command to verify if this is the case:

AVAILABLE DISK SELECTIONS:
0. c0t0d0
/sbus@3,0/SUNW,fas@3,8800000/sd@0,0
1. c2t1d0
/sbus@3,0/SUNW,fas@0,8800000/sd@1,0

If needed, the "public" and "private" lines from an output from vxdisk list c#t#d# of each device can be compared to confirm that the size is the same, although the disk will have to be initialized before this will work. (vxdisk list c#t#d# shows the same private/public configuration). Now that the disks have been established to be the same, an attempt can be made to manually mirror the volumes rather than use vxdiskadm:

The following is an example output of "vxdisk list" command:

DEVICE TYPE DISK GROUP STATUS
c0t0d0s2 sliced - - online
c2t1d0s2 sliced disk01 rootdg online
- - rootdisk rootdg removed was:c0t0d0s2

Run the following commands to completely remove the existence of the rootdisk in order to tidy up the configuration. This will involve disassociating plexes and removing the plexes with their associated subdisks:
Disassociate the plexes. This must be done with all plexes with a "STATE" of "DISABLED REMOVED". They must be done ONE AT A TIME. A plex can be located by looking for a "pl" in the far left column of information in the "vxprint -ht" output.
eg.
vxplex dis rootdiskvol-01
vxplex dis rootvol-01
vxplex dis swapvol-01


Run vxprint -ht to see that the plexes already disassociated
Remove the DISABLED REMOVED plexes and the rootdiskPriv subdisk.

eg.
vxedit -rf rm rootdiskvol-01
vxedit -rf rm rootvol-01
vxedit -rf rm swapvol-01

Remove the disk media name "rootdisk".
vxdg rmdisk rootdisk

Run a vxprint and make sure that all of the items from the "rootdisk" are removed (the original failed disk).

vxprint -htg rootdg


Once the vxprint shows that everything associated with the rootdisk has been removed, use vxdiskadm option 1 to initialize the new disk into rootdg (if not already done). DO NOT accept the default name. Instead, name it "rootdisk" (using the same diskname as previously). After the disk has been initialized, use vxdiskadm option 6 to mirror the volumes on a disk. This should automatically start the recovery process.

Solaris Replacing encapsulated root disk

[Replace the failed disk and boot the node:]

ok boot cdrom -s
...
[Use format and newfs to create partitions and file systems]
[Mount the root file system on a temporary mount point:]
# mount /dev/dsk/c0t0d0s0 /a
[Restore the root file system:]
# cd /a
# ufsrestore rvf /dev/rmt/0
# rm restoresymtable
[Create an empty install-db file:]
# touch /a/etc/vx/reconfig.d/state.d/install-db
[Edit /etc/system on the temporary file system and
remove or comment out the following entries:]
# rootdev:/pseudo/vxio@0:0
# set vxio:vol_rootdev_is_volume=1
[Edit /etc/vfstab on the temporary file system:]
Example:
Change from—
/dev/vx/dsk/rootdg/rootvol /dev/vx/rdsk/rootdg/rootvol / ufs 1 no-

Change to—
/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no -
[Unmount the temporary file system, then check the file system:]
# cd /
# umount /a
# fsck /dev/rdsk/c0t0d0s0
[Install a new boot block:]
# /usr/sbin/installboot /usr/platform/`uname \
-i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0

[Reboot:]
# reboot
[Update the disk ID:]
# cldevice repair /dev/rdsk/c0t0d0
[Encapsulate the disk::]
# vxinstall
Choose to encapsulate the root disk.
[If a conflict in minor number occurs, reminor the rootdg disk group
:]
# umount /global/.devices/node@nodeid
# vxdg reminor rootdg 100
# shutdown -g0 -i6 -y
