ProLiant DL580 G3

Good day,

I have 4 Emulex HBA's, 2 connected to disks and the remaining to the tapes. I noticed that one of the HBA's showing "link down" on HBAnyware and the LED status shows a flashing green light. Oops HBA's are LP9802. Yes, i have upgraded the firmware to the latest available (1.92A1 (H2D1.92A1), sli-2).
On one of the other HBAs which were connected to the tapes were suddenly not allowing me to rum any SCSI_INQ commands on them until i did a HBA reset through HBAnyware.
Am i having hardware related problems or are these SAN related. Where should i look ?

Hi,
I assume all the HBAs are directly attached to your tapes and disk array?
What is the OS and Patch level?

Hi Nuwan,

It's 2.6.18-53.el5, Red Hat Enterprise Linux Server release 5.1.
It's a switched fabric. And i'm connecting to a IBM tape library.
cheers

Hi,
Login to the SAN Sw and check if the systems wwns get registered on the switch.

If you can see the wwns of the HBA attached to the server form the SAN sw end, this means the HBA port is working.

Check for all wwns from SAN Sw end.

If all wwns able to see from the SAN Sw end this mostly means your HBA card is fine and working, so nothing to do with it

Other thing you have to check is the OS drivers and patches for the HBA.
Please rechek the release notes of the HBA/firmware regarding this.
Some times your new HBA might need new driver with new firmware.

Good Luck...!
