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,

d30

is the pre-migration boot disk, and

d24

is the

post-migration boot disk.

# scdidadm -l

...

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

d24

...

30 node1:/dev/rdsk/c8t50060E80004361D1d1 /dev/did/

rdsk/d30

15. Edit the post-migration boot disk's

/etc/vfstab

file, changing the swap device

definition from the pre-migration boot disk to the post-migration boot disk.
An example is shown below.
Before editing

/dev/dsk/c8t50060E80004361D1d1s1 - - swap -

no -

After editing

/dev/dsk/c0t0d0s1 - - swap - no -

16. Edit the post-migration boot disk's

/etc/dumpadm.conf

file, changing the

dump device definition in the

DUMPADM_DEVICE

parameter from the

pre-migration boot disk to the post-migration boot disk.
An example is shown below.
Before editing

DUMPADM_DEVICE=/dev/dsk/c8t50060E80004361D1d1s1

After editing

DUMPADM_DEVICE=/dev/dsk/c0t0d0s1
