I think the bootblock is not covered by the SVM sync process.

Hi, when i run this,
it show me
Code:
root@leo # /usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t1d0s0
/dev/rdsk/c1t1d0s0: Not writeable

Can you please check the access mode on the physical device? It should be something like

Code:
$ ls -lL /dev/rdsk/c1t1d0s0
crw-r-----   1 root     sys      118,  8 Jan  7 09:11 /dev/rdsk/c1t1d0s0

If you have to change the access mode, find the target of the symbolic link

Code:
$ ls -l /dev/dsk/c1t1d0s0
lrwxrwxrwx   1 root     root          70 Nov 17 14:37 /dev/dsk/c1t1d0s0 -> ../../devices/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w2100000c50ac8c6e,0:a

and change owner, group and access mode of that device to root, sys and 640. Then 'installboot' should work.

Yes, the access mode is same as yours. =)
any idea ?
erm... this should run before the mirroring or after ?
coz i haven do the mirroring yet. =)

Code:
root@leo # ls -lL /dev/rdsk/c1t1d0s0
crw-r-----   1 root     sys      118,  8 Jun 13  2005 /dev/rdsk/c1t1d0s0
root@leo # ^C
root@leo # ls -l /dev/dsk/c1t1d0s0
lrwxrwxrwx   1 root     root          70 Jun  9  2005 /dev/dsk/c1t1d0s0 -> ../.. /devices/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w21000011c6a75d1b,0:a

Strange! 'installboot' is a simple shellscript and one line reads as:
Code:
test ! -w $DEVICE && away 1 "$DEVICE: Not writeable"

It seems 'test -w /dev/rdsk/c1t1d0s0' is 'false' on your system.

Are there any errors logged in '/var/adm/messages'? And is the new vtoc already installed on the second disk?

Hi hergp

I think is the my PC and the server connection problem.
after I reconnect to the server again.

it able to run the shellscript
Code:
root@leo # /usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t1d0s0
root@leo #
