methods of reconfiguring lost DCO log volumes; choose the method that is appropriate for your
situation:
• Wait until the client is recovered and then execute the following VxVM command:
# vxassist -g rootdg addlog homevol logtype=dco Repeat execution
of this command until all the DCO volumes are restored.
Or
• Manually create an Ignite-UX configuration file that executes the VxVM commands as part of
the actual recovery process. This method integrates the VxVM commands into an Ignite-UX
configuration file.
For make_net_recovery, create a new Ignite-UX configuration file called /opt/ignite/
clients/0x<LLA>/recovery/config.local; while for make_tape_recovery, create
a new file called /var/opt/ignite/recovery/config.local. The respective
config.local file is automatically included in your recovery configuration for this client
each time make_net_recovery/make_tape_recovery is run.
An example of a config.local file that restores DCO log volumes after the recovery
completes follows:
###### Begin user changes to add DCO log volumes #######
post_config_cmd +="
vxassist -g rootdg addlog homevol logtype=dco
"
###### End user changes to add DCO log volumes ######
After creating this config.local file, it is a good practice to run instl_adm -T -f
config.local to ensure that the syntax is correct.
Commands in post_config_cmd are executed automatically after the client is restored.
Are the layered/striped/mirrored VxVM volumes included in the recovery archive
when a client recovery archive is created?
No. The make_tape_recovery and make_net_recovery tools do not back up the
layered/striped/mirrored VxVM volumes. You need to perform the following actions during and
after the recovery:
• During recovery, since the volume definition for layered/striped/mirrored volumes may not
exist, you might need to manually define a volume for recovery and resize other volumes
appropriately. Ignite-UX might have adjusted the size of other volumes so that the client can
be recovered. However, this might fail due to a lack of disk space and force an interactive
recovery. In any event, you must choose an interactive recovery then verify that the VxVM
volume layout will be appropriate after recovery.
• After recovery, recreate the original volume configuration. In other words, set up the previous
layered/striped/mirrored VxVM volume configuration.

Can I run make_tape_recovery/make_recovery in single user mode? If so,
how?
Yes. You can use these tools after booting or shutting down to single user mode. Choose the
appropriate procedure for your situation.
After you have booted to single user mode, use this procedure:
