Cause. This event was caused by a checksum error on a sector during a read
operation.
Effect. The data might be corrupted. However, if the data was recovered by reading
the mirror drive, $ZLOG will have the 'block rewritten' event (449).
Recovery. Run FCHECK against the file. If no errors are found, contact your service
provider, as directed by your local operating procedures (see Recovery Action
Requiring Vendor Support on page 11-20). If errors are found, recover the data by
whatever means available and contact your service provider.
For G-series RVUs and above, use the CONTROL DISK command. For more
information about the Storage Subsystem and SCF commands, see the SCF
Reference Manual.
