MD32xxi cause iSCSI lost connection if any of the connected host rebooted

Yesterday, another Taiwan customer called, and explain to me the issue as below. At first, I thought this is the correct behavior of the MD. However, customer told me HP storage wouldn't have this issue. I ask him to send in the Support bundle, and found that the NVSRAM isn't the latest one. Convince him to upgrade to latest, or at least to A03. Finally, customer willing to update.

Just received his email few minutes ago, knowing that the issue resolved after upgrade to A02. :-)

Implementation:

3 (three) PowerEdge R710 connect to MD3200i. All hosts installed with VMWare VSphere 4.0.

Issue:

Whenever one of the host rebooted, it will not detect the MD3200i. Customer need to power cycle all R710 and MD3200i, in order to ensure all hosts can detect the MD again.

Solution:

Ensure MD3200i's RAID Controller firmware is the latest, or at least version A02.
