MDDB.CF(4)

NAME

mddb.cf − metadisk state database replica locations

SYNOPSIS

/etc/opt/SUNWmd/mddb.cf

AVAILABILITY

This file is part of the Solstice DiskSuite software package (SUNWmd).

DESCRIPTION

The /etc/opt/SUNWmd/mddb.cf file is created when the metadb(1M) command is invoked. This file should never be edited by a user.

/etc/opt/SUNWmd/mddb.cf is used by metainit(1M) to find the locations of the metadevice state databases replicas.

Each metadevice state database replica has a unique entry in the /etc/opt/SUNWmd/mddb.cf file. Each entry contains the driver and minor unit numbers associated with the block physical device where a replica is stored. Each entry also contains the block number of the master block, which contains a list of all other blocks in the replica.

Metadevice state database replicas specified in /etc/opt/SUNWmd/mddb.cf are set up by metadb(1M).

Entries in the /etc/opt/SUNWmd/mddb.cf are of the form:

driver_name minor_t master_block checksum

where driver_name and minor_t represent the device number of the physical device storing this replica. master_block is the block number of the master block used by this replica of the metadevice state database. checksum is used to make certain the entry has not been corrupted. A pound sign (#) introduces a comment.

EXAMPLES

The following example shows a mddb.cf file.

#metadevice database replica location file do not hand edit
#driver   minor_t    daddr_t     checksum
id       3          16          -182
id       67         16          -246
id       18         16          -197
id       82         16          -261
