2 ESX Server and 2 mirrored Starwind server
Posted: Tue Apr 08, 2008 8:08 am
My configuration
2 ESX Server
2 mirrored Starwind server
Mirror Source
Device: Mirror0 (esxsan1)
Image file name: Mirror Volumes\D\iSCSI Volumes\esxsan1.mir
Total size: 4016 MB
First image path: D:\iSCSI Volumes\esxsan1.img (active)
First image state: Valid
Second image path: #iscsi:192.168.1.52:3260|TargetName=mirrorsan1|InitiatorName=3070ED0953B8BD590C65069585D3E5AC
Second image state: Valid
Read-only: No
Clustered: Yes
Persistent reservation: Yes
Mirrors are synchronized
Mirror Target
Device: ImageFile0 (mirrorsan1)
Image file name: My Computer\D\iSCSI Volumes\esxmirrorSAN2.img
Total size: 430000 MB
Asynchronous: Yes
Read-only: No
Clustered: Yes
Persistent reservation: Yes
I added both Starwind Servers to the iSCSI Software Adapter in the Dynamic Discovery.
Both targets are now shown in the iSCSI Software Adapter.
after that a added the esxsan1 target to the storage of the esx servers.
but when i also add the mirrorsan1 target to the storage of the esx servers i have to format it.
This is not the worst problem because if you start with a new Partition things went well.
Both SAN´s are now browseable. And everything is being synchronized like it should be.
So far this is what i expected.
The Background is that if the first SAN becomes unavailable i can switch to the second san and start the Virtuell Machines.
So i am able to keep the server running with very short down time.
Sure if this happens i have to reconfigure the Mirroring between the two sans but i do not need to wait until the complete esxsan1 is recovered from the mirrorsan1.
And now the big problem i got.
if the mirrors need to be synchronized manually with the command "Check and Synchronize.."
the mirrorsan1 disappears in the storage configuration of all esx servers.
And when i want to add this disk again, i have to format it and everything is lost on this disk.
To get all things work well again i have to move everything from esxsan1 to anywhere and back again to the esxsan1 to get the moirroring working right again.
So what can i do to prevent this disk from beeing formated by the esx server.
Is there a solution for this problem or do i have to change my configuration.
Best Regards
