Hi,
Thanks for the reply.
Yes, I am sure the replication disks are EFI labelled using format -e.
There is no special reason why we use 36gb as primary and 146gb as secondary.
We cannot find identical hard disk at the time of testing. 146gb disk is set as
secondary simply because it is bigger than the primary disk.
1. The bitmap volume for primary:
$ dsbitmap -r /dev/rdsk/c0t9d0s0
Remote Mirror bitmap sizing
Data volume (/dev/rdsk/c0t9d0s0) size: 71116508 blocks
Required bitmap volume size:
Sync replication: 273 blocks
Async replication with memory queue: 273 blocks
Async replication with disk queue: 2449 blocks
Async replication with disk queue and 32 bit refcount: 8977 blocks

The volume is a slide in another disk.

Do I have to use identical disk for SNDR replica? Can I use partition for
bitmap volume?
Thank you.
