Please, some one help me….!!! I screw up big time. I was doing the Hastctl create disk2 But since I got some input out errors I decided to stop /etc/rc.d/hastd stop But since couldn’t stop disk1 and 9 I killed it. Restarted both servers. And now only /dev/hast shows nothing. And the pool is lost. I was able to create disk2. I have restarted both server but the pool is not coming up. Any suggestions, please help I know that the info is there since I only did “hastctl create disk2” I haven’t done it for the other disks. From: Jose A.

I still have a small problem, and I'm not sure if it is because hastd is running. I can't initialize (hastctl create disk2) disk2 This is what I did. 1.. zpool offline tank /dev/dsk/hast/disk2 2. zpool status -x [root_at_san /usr/home/jose]# zpool status -x pool: tank state: DEGRADED status: One or more devices has been taken offline by the administrator.

Once that is done, the /dev/hast/disk2 GEOM device node will be created. Then you can 'zpool replace' it. One step at a time. :) And you've skipped a few. 1. 'zpool offline' the defective disk 2. Physically remove the defective disk 3. Physically insert the new disk 4. Initialise it as a HAST resource via 'hastctl' 5. 'zpool replace' it using the /dev/hast node 6. Wait for the pool (and HAST) to resilver it 7.
