3G SAS switch to MDS600 unable to connect due to SSA70 path failure

We are having trouble connecting our MDS600 to the 3G SAS switch c7000 in a single domain setup. We are getting the following errors. We have viewed all of the documentation and are unable to find any references to this error. Does anyone have any ideas?

Re: 3G SAS switch to MDS600 unable to connect due to SSA70 path failure

Have you cabled correctly?
Have you zoned the MDS?

I have no knowledge on the SSA 70.

But I have setup a system with P700m.

If you got a FW ver.1.xx on the SAS switch, it can't be zoned.
If you got a FW ver. 2.xx It must be zoned.

Also you must have the minimum FW rev. on the MDS for the ver. 2.xx to communcate with the MDS.

Once the MDS and SAS switches is at the minimum FW levels.
You must Zone the MDS, and assign the zones to the appropriate server(s)

The Zoning is done on the SAS switch.

Re: 3G SAS switch to MDS600 unable to connect due to SSA70 path failure

yes, it is cabled according to the documenation and I'm using the P700m Controller. http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01956983/c01956983.pdf

Yes, we created the zone. But the problem occurs immediately during start up. In the Virtual SAS Manager, I get the following alert on HP 3G SAS Blade Switch 5: VSM Active: Code 452 Storage Enclosure at Port:51 Box:1 is degraded because of a path failure.

The firmware on the 3G SAS Blade is 2.2.4.0 and the firmware on the MDS600 is 1.42. I'm unable to upgrade the firmware on the MDS600 because it says the path is degraded. I tried downgrading the firmware on the SAS and I still was unable to connect to the MDS600 for firmware upgrade.

"The firmware on the 3G SAS Blade is 2.2.4.0 and the firmware on the MDS600 is 1.42."
Here's the Reason for your problem

I had to follow the instructions below:

You might have to do the same.

Re: 3G SAS switch to MDS600 unable to connect due to SSA70 path failure

To save you some sweat.

This is not an exact how to. You will need to read the abaove links.

Read it before you read this.

I did this in dec 09/jan 10.
Using FW CD 8.60.

Download FW CD 8.60
Create FW CD on an USB memory stick.

Download 2.54 FW for the MDS (See Link)
Copy fw fw1244.scexe into the \compaq\swpackages folder.

Download Switch FW 1.1.8.xx

Depending on you configuration
Chhose how to do it.

If you got a C7000 and a SAS switch in IC Bay 3 and 4.
Remove the switch in bay 3.
Connect all cables to the swictch in bay 4.
Downgrade the switch to 1.1.8.x

Boot a blade with a Smart Array ctrl (Not the onboard)on the USb mem.
Enter debug mode - At the first screen hold down the CTRL key, and enter D B X
waite a few seconds and you get a Linux command prompt.

Change to the swpacakes folder
\opt\bootdev\compaq\swpackages
Enter the following command
sh FWfile.scexe
Then follow screen
Once the MDS has been upgraded to 2.54.
You can upgrade the SAS switch again.
Remove the switch.
Put switch 3 back
put switch 4 back
connect all cables correctly.

Usinge the SAS switch manager.
Upgrade MDS to 2.66
Upgrade SAS switches to latest.

Don't try to be a wiseguy, it might punish you.

christopherrmilton,

Did you solve this problem? I'm currently having the same problem myself.

Yes, when i run the update in debug it says no devices were updated. It pretty much ignores the storage enclosure.

Re: 3G SAS switch to MDS600 unable to connect due to SSA70 path failure

Actually, we ended up configuring for dual domain setup and the I/O modules we had didn't support dual domain. Also, the HP engineer tried to upgrade the firmware by connecting to a SAS port on a Proliant server. This also wasn't successful for us but worth trying if you have an available Proliant with SAS port.
