DSA disk errors

James Buttitta — Tue, 06 Sep 2005 09:06:57 GMT

Running OpenVMS 7.3-2. Getting lots of DSA errors. HP recommends running analyze/disk/read to determine if there is a corrupted file. Results show Informational & warnings but no fatal errors. We have like configurations (HW & SW) at other sites that are running just fine. Latest system-700 patch has been applied.

$ ANAL/DISK/READ will read all allocated blocks and report any problems. This will check if there are blocks in a file which can't be read.
Can you post the results of the ANAL/DISK/READ command (ideally as an text file attachment to your response to preserve formatting) then some futher assistance is possible.

There have also been some SHADOW patches released. Which VMS732_UPDATE and VMS732_SHADOWING patches do you have installed?

Have you tried running the DFU VERIFY tool against this device as well? Are the errors on the DSA device name or the component member drives? If you do a SHOW ERROR do you see only the DSA device name listed or do you also see the members? What kind of drives are the members? If they are SCSI drives direct attached to the system you will also want VMS732_FIBRE_SCSI V7.0.

There is also the ANALYZE/DISK/SHADOW command

For checking that the shadow set members are consistant.
