MSA1510i - iSCSI target not reconnected after boot

I'm using vsphere ESXi 4.0, updated to last patch as of today, and I'm having this problem.
Any iSCSI vmfs disk is not reconnected anymore after reboot.
If I perform a manual rescan, all disks are mounted again, but no hope to see them before the manual rescan.
4 disk sets on 4 NICs on MSA1510i (active/active), each disk-set with two paths.
Each server has 4 NIC for iSCSI.
All paths are manual and fixed.
After manual rescan, I see 32 connections on MSA1510i (4 disks, 4 servers, double path), as it should be.
There was no problem up to a few days ago, before installing last vsphere patches (I had to do because I needed a patch for loss of vkernel connection).
Any hint?

Re: MSA1510i - iSCSI target not reconnected after boot

Hello,
strange issue. My sugestions:
a) is raise a call to vmware if you have support for it.
b) check vmkernel logs if there is something strange
c) check firmware level of your MSA - just to make sure this is not the root cause

Re: MSA1510i - iSCSI target not reconnected after boot

Problem solved, but it looks strange anyway.

Believe it or not :.) :
If I make a rescan and reboot, no iSCSI disks.
If I do a reboot without any previous rescan, iSCSI disks are correctly mounted.

DNS disabled for having more speed.
Reboot... rescan ... reboot -> no iSCSI disks
Reboot ... reboot -> iSCSI disks mounted

After dozens of reboot... it works in this way.
