Udayan,
Have installed AVS-i386-20070202 and were going through
the released pdf notes on the availability suite ref: http://
www.sun.com/hwdocs and have reached Initial Configuration
Procedures but now are unable to use bitmap volumes as given in
your notes i.e.-
To obtain the size of a Point-in-Time Copy bitmap, use this command:
dsbitmap -p data-volume [bitmap-volume]
we don’t know the data-volume and bitmap volume in our
system and want the procedure to create and use data and bitmap
volumes.
The "data-volume", is the source volume of the Point-in-time copy.
The "bitmap-volume" is an optional argument to the dsbitmap utility,
and can be ignored.
Therefore if your "data-volume" is dev/rdsk/c4t3d7s0, this is the
typical output from dsbitmap:
# dsbitmap -p /dev/rdsk/c4t3d7s0
Point in Time bitmap sizing
Data volume (/dev/rdsk/c4t3d7s0) size: 285196221 blocks
Required bitmap volume size:
Independent shadow: 2222 blocks
Full size dependent shadow: 2222 blocks
Compact dependent shadow: 37518 blocks
What this output means, is that if your Point-in-time copy data-
volume is 285196221 blocks, and you want either an independent or
(full size) dependent shadow, you will need to provision two volumes:
1) A volume 2222 blocks in size needs to be provisioned for the
bitmap volume, for example /dev/rdsk/c4t3d6s1
2). A volume 285196221 blocks in size needs to be provisioned for the
shadow volume, for example /dev/rdsk/c4t3d6s0
Now the independent (or dependent) shadow set can be enabled:
iiadm -e ind /dev/rdsk/c4t3d7s0 /dev/rdsk/c4t3d6s0 /dev/rdsk/c4t3d6s
If you wanted a compact dependent shadow volume, at step 1 above, you
would have had to providion a 37518 block volume, then
iiadm -e dep /dev/rdsk/c4t3d7s0 /dev/rdsk/c4t3d6s0 /dev/rdsk/c4t3d6s
Of course this is an example, and the master, shadow and bitmap
volumes could be any Solaris block device, on any storage.
Any help would be great
Tia,
Udayan
