Lost Logical Drive in HA SAN

Hi,
I'm using Starwinds San 6 and have lost a logical drive belonging to a HA cluster. I'm pretty sure I have to remove the device and re add it but I'm not to sure how to do this safely. I see two options

1: in the failed server select Devices and Right Click on the HA image and select "Remove Device"

2: in the non failed server; Select device ; Select non failed HA image; Select Replication Manager ; Remove Replication Partner ; Then add replication partner.

Am kind of guessing option 2. I in the right ballpark here or am I about to destroy my good drive as well..

Any help would be much appreciated.

Thanks

Hello Adam,
The way you have proposed to restore HA device is correct.
There are several additional steps to make it completed:
1: On the failed server select Devices and Right Click on the HA image and select "Remove Device"
2: On the failed server select Target for failed device and Right Click on it and select "Remove Target"
3: On the non-failed server; Select device ; Select non-failed HA image; Select Replication Manager ; Remove Replica; Add replica; Type the host name/ip address; Specify the name for the virtual disk on the second server in a format "My Computer\D\STARWIND\TEST_HA.img", check "Create new" and specify exact Size of device that you have on non-failed server; Select channels for Synchronization and Hearbeat and complete the wizard.
4: Wait while synchronization process will be completed and device on a failed server will be "Synchronized"
5: Connect newly created and "Synchronized" device in iSCSI Initiator.

Thanks Michael,
I just got back from break today, (13 days off). I followed your instructions and it worked pretty smoothly. The only things weren't 100% sure of were the following. So here are some notes for anyone else following this in the future.

The image name to choose was the image on the failed server. I.E: If node b failed then the image was "My computer\d\nodeB.img"
The names of the new device names are incremented. I.E: The original Device names where HAImage1 & HAImage2 These are now HAImage3 and HAImage4. On the second server.
So now Device Server1\HAImage1 = Server2\HAImage3

Apart from that all went very smoothly.

Thanks for all you help

Adam
