NAME

mirrortab − mirror disk-log format

Remarks:

Mirror facilities require installation of optional DataPair/800 software (not included in the standard HP-UX operating system) before they can be used. 

DESCRIPTION

Mirrortab is a file describing all mirrors on the system.  This file is created and maintained by the daemon mirlog(1m).

There is one line in the file for each mirror.  Each line contains the following blank-separated fields in the order shown (see mirror(1m) for definitions of terms):

primary device Pathname of the primary section of the mirror.  The name of the mirror is the same as the name of the primary device. 

primary state State of the primary section of the mirror.  Possible values are ONLINE, indicating that the section is in operation; OFFLINE, indicating that the section is not available for use; and REIMAGE, indicating that the section is in the process of being brought into agreement with its ONLINE counterpart. 

secondary device Pathname of the secondary section of the mirror pair. 

secondary state State of the secondary section of the mirror pair.  Possible values are as described for primarystate. 

fail Mirror fail flag.  Possible values are GOOD, indicating that neither of the sections making up the mirror pair has experienced a failure, and FAIL, indicating that one of the sections making up the mirror pair has failed, and thus is OFFLINE. 

clean Mirror clean flag.  Possible values are CLEAN, indicating that the two sections making up the mirror pair are guaranteed to be identical, and DIRTY, indicating that the sections may differ.
