BL460C Windows 2003 R2 EMC CX340 : shutdown Problem

[Danel_1]

Hi ,

I must connect blade servers (bl460c) on san to use Emc volumes (CX340 Array) .

the software mandatory by Emc and used are :
- Windows 2003 R2 Us
- KB916048
- driver 9.1.2.19 for qlogic hba QHM2462
- PowerPatg 4.6.1
- Navisagent 6.22

The Problem is :
When i want to shutdown a sever , the server hang during the shut and i must reset the blade to reboot.
If i remove the KB916048 to come back with original storport.sys (R2) all is fine :
the reboot run correctly , but EMC don't support this.

the KB923801 or KB932755 don't change anything.

Can anyone help me to debug this issue , it' s very urgent.

Thank very well

Hi.
I had a problem very similar to yours, and found a solution (or more correct a way around it)
First, are you using MPIO?
Thats when my problem started.

Hi again.
Here is what I did:

It seems that the problem arrived on my servers because the FC driver for qlogic (ql2300.sys) loads to early during boot so it doesnt get registered correctly with the MPIO.

You can test this by disable and then enable the HBA's. Then it shutdowns correctly I suppose.

Both the MPIO.sys and the ql2300.sys is loaded by the kernel loader. (start type 0).
Try change the FC-driver (ql2300.sys) to load after the mpio.sys has loaded, by setting it to start type 1 wich means it is loaded by the I/O subsystem during boot.
Do this by changing the following registry key to 1 instead of 0:

HKLM\system\CurrentControlSet\Services\ql2300: Start=1

This worked great for me on several servers and have'nt had any errors or trouble since then.
I am not sure if this solution is supported since it's just a "way around" , but I spoke to HP support and they didnt seem to have any problems with it.

Hope this could help.

Hello ,

Thank you very well for your help.

after the modification on the QL2300 in the registry , all the servers can restart correctly.

I don't know where you found this information , but it 's very important for me , my project can continue now.

Thank very well.
