HP 1:10Gb Ethernet Blade Switch degraded

[OliverAn]

Hi,

We have a problem in our C7000 Enclosure: The HP 1:10Gb Ethernet Blade Switch in Bay 1 goes to degraded state after some days of operation. I can't find any further errors, but OA syslog shows:

Interconnect 1 selftest: Interface micro is not responding

Interconnect 1 selftest: FRU is not responding

When I transfer OA passive to active the switch is shown as faulty and I am unable to power on any blade.

We have already replaced the switch and also the midplane, firmwares are all up to date. Any suggestions what to check?

Try re-siting the switch first. Might help.

Hi

Any  new about this topic because i have the same  problem ?

This problem is occuring on several blade center and only with HP 1:10Gb Ethernet Blade Switch.

Network activities work fine but a error is reported by OA

Thanks

Hi Eric,

We opened a support call at HP that is still in progress. They say that it is related to the fact that we have 1:10 in Interconnect 1 and GbE2c in Interconnect 2. I have not seen any documentation that sais this is an unsupported configuration.

How are your Chassis configured, what Interconnect Modules do you have?

Hi

This problem occurs inside three switchs 1:10 installed on 2 blade center

The first blade center has an 1:10 switch on interconnect 1 and  a switch GbE2c on interconnect 2

The second one has two  1:10 switchs on interconnect 1 and 2 and two switchs GbE2c on interconnect 3 and 4

Of course  firmwares/bios/OA/... are up to date and my HP contact has no answer to me. When i unplug and re-plug the switch no alarm occurs during some hours but after a couple of days all the 1:10  switchs are on alarm

Okay, that's interesting. HP told us that we may not use 1:10 and GbE2c in adjacent bays, but I see you get the same errors on your chassis with 1:10 in 1+2. For me it''s the same, if we pull the switch out and put it in again everything works fine - even for 2-3 months.

Did you open an official call?

Hi

Bad new, the version of OA 3.32 doesn't solve this issue: After update of OA and re-siting of switch,  same error occurs after some hours.
