FC10 Controller Error

Dennis Raesner_2 — Tue, 25 Jan 2005 11:18:26 GMT

We were instructed to remove a RP7410 off EMC Symmetrix storage, and what we had available for replacement was an HP FC10 730 GB storage unit.

Now we're getting a daily email from EMS as follows, but if you go into xstm the log report is not showing any errors so the controller/s is not actually producing any errors although EMS is reporting an error.

Has anyone seen this before? Can this be an EMS issue?

Thanks,
Dennis Raesner

To possibilities that I can see.

1) There actually is a hardware flaw on the array.
2) There is no LUN0 assigned on the array and the disk array itself is being misdectected as a disk. Since its not a disk, it has disk errors.

Solutions:
1) Resolve the hardware issue(not likely there is one)
2) Assign a LUN on the array to LUN0
3) Ignore the error, if I'm right its not serious.

Hi

Controller will have a fail LED .
See if its glowing .

If LED is lit then you have to call HP support.

Thanks,

Right, the email is a nuisance, and XSTM is not reporting any errors on either of the controllers for the HP FC10. So there does not appear to be any true hardware errors as far as I can tell even though EMS is reporting an error.

The information log from MSTM is listed below:

Steven:

Why would you want to assign a LUN on the array to LUN0 in this case. This is a HP FC10 fibre channel JBOD with 10 disks - not a SAN?

Any other ideas?
