Failure effect
OpenVMS—OS will report the volume in a Mount Verify state until
the MVTIMEOUT limit is exceeded, when it then marks the volume
as Mount Verify Timeout. No data is lost or corrupted.
Tru64 UNIX—All I/O operations halted. I/O errors are returned
back to the applications. An I/O failure to the system disk can cause
the system to panic. Possible data loss from unfinished or unflushed
writes. File system check may be needed upon reboot.
OpenVMS—OS will report the volume in a Mount Verify state until
the MVTIMEOUT limit is exceeded, when it then marks the volume
as Mount Verify Timeout. No data is lost or corrupted.
Tru64 UNIX—I/O fails over to the surviving path. No data is lost
or corrupted.
Failure effect
OS reboots. When mounting volumes, volume repair or NSS rebuild
executes to cleanup volumes. Data loss, data that finished writing
survived.
