iSCSI + vfstab

What is the preferred way to persistently mount an iSCSI device in Solaris
10?

For example, I'm utilizing an HP P4000 storage system (LeftHand).  I have
created the iSCSI volumes and configuration as desired on the HP/Lefthand
CMC.
I'd like to confirm that my Solaris configuration correct.  Testing in
production here :)

# cat /etc/vfstab
/dev/dsk/c4t13d0s6      /dev/rdsk/c4t13d0s6    /my_iscsi_mount    ufs     3
iscsi   noatime

# ls -ld /dev/dsk/c4t13d0s2
lrwxrwxrwx   1 root     root         105 Sep 17 17:55 /dev/dsk/c4t13d0s2 ->
../../devices/iscsi/[email protected]%3Amgrgroup01%3A
267%3Agap091rpz060001,0:c

# ls -ld /dev/rdsk/c4t13d0s2
lrwxrwxrwx   1 root     root         109 Sep 17 17:55 /dev/rdsk/c4t13d0s2 ->
../../devices/iscsi/[email protected]%3Amgrgroup01%3A
267%3Agap091rpz060001,0:c,raw

Can anything change the numbering of device (the c4t13d0s6) files?
If add or remove volumes from the HP/Lefthand storage, can this change the
device numbering in Solaris?
Is this device persistent and vfstab valid across reboots?
