MSA1510i - iSCSI target not reconnected after boot

[Antonio_73]

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?

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

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.
