Upgrade to 6.0up35.8101.4452 64bit - Lost iSCSI connections

Have you created the LUNs with DSSv6 (with SCST)? Otherwise the following KB article will help you.

Perhaps a resignaturing which is described here can help. This works only in ESXi 3.5.

Hi! Yes, the LUNs were created originally on a DSSv6... version 3536 or something, don't quite remember.

All of the LUNs are visible and the volumes show up in ESX4 when I'm on 4221. As soon as I upgrade to 4452 they disappear and the only way I can get them back is to revert back to 4452.

I'm wondering if this is a config problem, are there any major config changes since 4221 to the new version that would cause this kind of problem?

I did notice that if I tried to remove targets in 4452 or add additional targets, the page would just refresh and nothing would happen.

I was able to get to 4362 by removing all ESX Volumes, Deleting all Volumes from Volume Groups in DSSv6, recreating all volumes as Block I/O instead of File I/O and then representing those to ESX4.

I then upgraded from 4221 to 4362 and the volumes are still present and LUNs still connecting to ESX.

I will try to 4452 upgrade now and post the results.

Upgrade to 4452 worked perfectly when using Block I/O rather than File I/O...

Apparently VMWare is less picky with Block targets.
