Can someone please help me correct steps to remove SAN Luns.

I have already stopped Application and oracle running on this system.

now I want to unmount partitions (only from SAN) and remove any configuration for SAN so that reboot will not show the disks or try to mount.

Please help!
Thanks

hi,

that should work:
umount them and then issue this command:
# cfgadm -o force_update -c unconfigure c4::5006016130206b9d
# cfgadm -o force_update -c unconfigure c4

and the same for every controller. it that doesn't work, just disconnect the cables, then you will see:
c4::5006016130206b9d,0 disk connected configured unusable

when it is marked as "unusable" you can use that:
# cfgadm -o unusable_FCP_dev -c unconfigure c4::5006016130206b9d

to remove the "dev" entries, you should also use:
# devfsadm -Cv

kind regards
