3. Creating an HDLM Environment

7.

Set the

rootdev

parameter for the slice containing the

/

(

root

) file system of

the post-migration boot disk to the

/etc/system

file of the post-migration boot

disk.
In the

rootde

v parameter, specify the physical device file name of the HDLM

device. In the following example, the underlined part is the physical device file

name displayed in the execution example in step 6.


rootdev:/pseudo/dlmndrv@1/dlmfdrv@w50060e80004361d1,1:a

8.

Edit the post-migration boot disk's

/etc/vfstab

file, changing the Solaris file

system to the HDLM logical device file name of the post-migration boot disk. If
using Sun Cluster, change the mount device

#

of the Sun Cluster global device file

system in the same way.
An example is shown below.
Before editing

/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no -

/dev/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /usr ufs 1 no -

/dev/did/dsk/d24s3 /dev/did/rdsk/d24s3 /global/

.devices/node@1 ufs 2 no global

After editing

/dev/dsk/c8t50060E80004361D1d1s0 /dev/rdsk/

c8t50060E80004361D1d1s0 / ufs 1 no -

/dev/dsk/c8t50060E80004361D1d1s6 /dev/rdsk/

c8t50060E80004361D1d1s6 /usr ufs 1 no -

/dev/did/dsk/d30s3 /dev/did/rdsk/d30s3 /global/

.devices/node@1 ufs 2 no global

#

Execute the

scdidadm

-l

command to find out the device ID to specify as

the mount device of the Sun Cluster global device file system. In the

following example,

d24

is the pre-migration boot disk, and

d30

is the

post-migration boot disk.

# scdidadm -l

...

24 node1:/dev/rdsk/c0t0d0 /dev/did/rdsk/
