Solaris 10 Volume Manager - adding slice to metadb
Hi all,
I added a new disk slice to the current metadb.
Below is what I see
Code:
bash-3.2# metadb -i
flags first blk block count
a m p luo 16 8192 /dev/dsk/c0t0d0s7
a p luo 8208 8192 /dev/dsk/c0t0d0s7
a p luo 16400 8192 /dev/dsk/c0t0d0s7
a p luo 16 8192 /dev/dsk/c0t1d0s7
a p luo 8208 8192 /dev/dsk/c0t1d0s7
a p luo 16400 8192 /dev/dsk/c0t1d0s7
a u 16 8192 /dev/dsk/c0t2d0s7
a u 8208 8192 /dev/dsk/c0t2d0s7
a u 16400 8192 /dev/dsk/c0t2d0s7
I am missing the following flags.
p - replica's location was patched in kernel
l - locator for this replica was read successfully
o - replica active prior to last mddb configuration change
q1) Can anyone elaborate the meaning of 'p' and 'l' especially ?
These flags get added during next boot. As long as you see "u" flag for the new disk and no "UPPERCASE" flags (ie. WMDFSRB) present you are good with SVM.
Just ensure the
Code:
metadevadm -u <cXtXdX>
command executed after any disk change with the replaced device name. This command update the device relocation information. You can check this by running

Hi rinjohn,
Thanks for your reply. If I have done the following
Code:
1) remove the metadevice of the old disk/slice
2) remove the slice of old disk from metadb
3) replace old disk with new disk
4) add the slice of the new disk to metadb
5) recreate a metadevice
Do I still need to issue metadevadm ? -- thought when I add the new slice to metadb , the deviceID will be added automatically ?

d2: Concat/Stripe ---- Interlace value is 32 KB
Size: 2923830 blocks (1.4 GB)
Stripe 0: (interlace: 64 blocks)
