I can not say for sure why your getting this error, but it could be related to a bus reset.

If you want, I can review some SAN documentation that you would have to put together. Things like your switch configuration and your hsg80 config.

HSZDisk is one of the intermediate drivers that Compaq uses on Windows 2000 to present SAN based storage to the host. If you lose access to a disk for some reason, an HSZ error will occur. If you see this on multiple servers at arond the same instance, it could mean that aside from the disk error, you probably have some SAN switch zoning issues.
