I everyone
i've a san environment with eva, blade , and MSL5000 attached to a san

153. 07/01/2005 01:44:18 7d10h57m31.65s SCSI port 1 invalid DSA
154. 07/01/2005 01:44:18 7d10h57m31.65s SCSI port 1 invalid DSA

Re: msl 5000 errors

Depending on the backup sw type disable removable storage service in windows, and patch fibre array agent ( management agents) with the patch available on hp.com, to stop all unnecesary trafic on the san ( scsi resets and so on...)

The customer use Brightstor 11r1 and i've disable fibre agent, but the problem persist and it's random problem,of course the RSM is disable.

Re: msl 5000 errors

Hi,
invalid DSA is indicating an error on the scsi bus connected to port one.
It would be nice to know if you have other correlate messages in the traces.
In my experience, I got similare error in two cases:
-with hardware connection problems on the scsi bus or on the communication part of the drive itself, when messages like HTH errors are presents.
-With sw conflict when messages like Reservation Conflict appear in the traces.

I suggest you to check for scsi cabling in the first case,
and check if RSM is stopped an all servers connected to the SAN, + insight agents upgraded to 7.20 with Tape agent disable(W2K) or OV-SAM patched if UX + Zoning implemented in the second case

Re: msl 5000 errors

Hi, I'm having the exact same problem on my e1200 in my MSL5026 connected to my SAN fibre switch! Did you find anything that resolved the problem? I've tried swtiching the tape drive on SCSI port 1 no go. Then I switched the drives between themselves and had the same problem which leads me to believe it may be some kind of SCSI hardware problem.

Thanks

Re: msl 5000 errors

Hello Daniele,

1. Check with any backup client for enabled local SCSI backup drive, if so please disable the local drive (mostly on windows client)
**You can see the errlogs of Backup SW and make sure which clent is making exact SCSI problem.

2. Re install/reconfigure the backup client S.W if necessary.

Hope this may help you resolving the problem
