[Info-vax] DKA0 AND PKA0 errors. How to diagnose?

I always find this stuff confusing.  I got 2 PKA0 errors and 1 DKA0 error that same time.  Could someone interpret this?

This is on a DS10 running VMS7.3-2.  DKA0 is in a shadowset.

I guess I had a soft error on DKA0?  But why the PKA0 errors?

I can replace DKA0 with a new disk I have (I mean new new, not a refurb).  But I am never sure what to replace when I get this kind of error.  I could swap out PKA0 for another old SCSI card that I have.  I could replace the SCSI cable if it's old, but I think a have a new one in this computer.  I could just reseat the cables (the SCSI cables don't lock in place so they sometimes can need reseating.)

BTW, is it possible to buy a new SCSI card for a DS10?
