Hi All,
We are running an exchange cluster on two Proliant DL380 G2. Recently,we ran into several event viewer errors, for examples:

The driver for device \Device\Scsi\lpxnds1 detected a port timeout due to prolonged inactivity. All associated busses were reset in an effort to clear the condition.

Event Type: Error
Event Source: hpap
Description:
An unrecoverable path failure occurred on SCSI address Port 4 P1 T1 L33. Device \Device\Scsi\Hp_MpIo0Port0Path0Target4Lun33 is still accessible over the redundant path(s).

Obviously that looks bad, but the server is still running ok for now.

I too am having the same issues. Please post any reply or solution. Thank you.

Looks like you have multiple paths to one disk device, for example dual HBAs, and one of the paths is not working (hba failure, cable, switch port), or one of the storage controllers is having problems.

Start a hardware revision.

I have the same Problem and now i need to know what solves this failure.
Was it from the MPIO DSM Software (update) or from one of the switches/calbes...

Thanks for your response.
