Set the LU slices to be used by the post-migration boot disk.

4.

Execute the

dlmsetconf

utility as follows to create the HDLM driver

configuration definition file (

/kernel/drv/dlmfdrv.conf

) and the HDLM

driver unconfiguration definition file (

/opt/DynamicLinkManager/config/

dlmfdrv.unconf

):


# /opt/DynamicLinkManager/bin/dlmsetconf

This step and the next step set the LU to be used for the post-migration boot disk

as an HDLM-managed LU.

# reboot -- -r

boot -r

(at the
