How to replace boot disk on Solaris T2000

On OK prompt:

<ok> select /[email protected]/[email protected]/[email protected]/[email protected] scsi-pci1000,56 LSI,1064E scsi-pci1000,56 ?
|—————-controller———|  |—alias1——–| |–alias2–|  |—alias3——–|  ?
<ok> show-volumes
(Here we should have the list of RAID Volumes)

<ok> 0 activate-volume
(activates the selected volume)
<ok> boot

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
<ok> show-disks
a) /[email protected]/[email protected]/[email protected]/[email protected]/[email protected]/cdrom
b) /[email protected]/[email protected]/[email protected]/[email protected]/[email protected]/disk
c) /[email protected]/[email protected]/[email protected]/[email protected]/disk
q) NO SELECTION

<ok> select /[email protected]/[email protected]/[email protected]/[email protected]
(/[email protected]/[email protected]/[email protected]/[email protected] is the controller)

<ok> setenv fcode-debug? true
(enables extra commands like the following)

After controller selection, you can see the disk with:

<ok> show-children

<ok>boot net -s ( Single User Mode boot for recovery)
