EMC Fibre Channel Throughput

[Kurt Dickason]

Is there some additional configuration that EMC needs to perform on 3430 frame after upgrading to Tachyon Fibre Channel Adapter(A5158A)?

Severe throughput degradation occurs after about 96 hours of operation on FC link. Failover to alternate SCSI link and all runs well. Replaced FC card, updated to latest FC driver. HP Tech passed FC cable.

Kurt,

Check with EMC for firmware upgrades.

Check for HP patches using custom patch manager.

EMC says that the firmware rev is within spec.

Kurt,

You could have a bad gbic or fibre card. I'm going to coin a phrase here, "gbic's die, that's no lie". gbic's are flaky, and when one goes, replace them all.

The GBIC was replaced with the Fibre Channel card last month. Same result.
