SureStore 4/60, SAN, Win2K - Somewhat Urgent
I have Win2K server connected to the HP SureStore 4/60 via Brocade FC16B using Emulex LP9002 HBAs, as soon as the server is connected to the switch I am getting high amount of 'Encd Errs Outside Frames' on the two ports that the Library is connected too. Also, I am loosing dirves on other hosts (HP-UX & Win)at random intervals which creates unstable environment, once the server is unpluged everything gets back to normal. So far I had verified that the HBAs have the correct drivers, correct drivers parameters, as well as the Firmware. The RMS is disabled on the Win2K server. It appears that 'something' is pooling the library/other hosts causing SCSI restes and the drives to go down, there is nothing conclusive in the event logs.
One more thing, every time the server is rebooted it will pick the robotic arm on the library and ask for drivers (there are none), can this device be disabled from Win since HP-UX Master server is controlling the arm?
Should any services on the Win2K box be disabled?
I would appreciate if anybody could help!
Thank you,
Witold

Does the win2k server have any backup software on it (like Backup Exec?)
These can interfere horribly with SAN tape devices, as many windows backup products 'assume' they have dedicated access to the drives/robot and issue SCSI reserves etc.

The server has Veritas NetBackup Datacenter 4.5 FP5 installed as a Media Server, the Master server is controlling the robotic arm. The backup runs via HBA

this agents (Scsi agent and/or FC agents) may some time interfere with san.
I suggenst you as a troubeshooting test to desable any monitoring tool that can run on that server

Re: SureStore 4/60, SAN, Win2K - Somewhat Urgent
However, I can't find good information to say for sure whether these are talking the same FCP language. This may be configurable on the Emulex itself - I just don't know.
Given the way that I guess this library sits on the SAN, it won't be possible for you to block your server from seeing the arm without blocking it from seeing the drives. Not unless you can limit the SCSI IDs which it sees, but I don't think that's possible.
Not much conclusive there - hope it gives you something to look at though.

Re: SureStore 4/60, SAN, Win2K - Somewhat Urgent
I have used a similar library (2/20) in a SAN enviroment but with a Qlogic HBA. Qlogic has a SAN masking tool which makes it possible for the host to see the drives but not the robotics. I am sure there is a similar tool for Emulex HBA.

Re: SureStore 4/60, SAN, Win2K - Somewhat Urgent
After opening a call with HP for the re-discovery of the robotic arm after every re-boot, I've got the following answer: Sir, the recommended solution is to ignore the behavior - I find that amusing.
Can yo be more specific about the software/utility to block the visibility to the robotic arm?
Thank you,
Witold
