ASMLib on Multipath Disks

The configuration file contains many configuration variables. The ORACLEASM_SCANORDER variable specifies disks to be scanned first.

The ORACLEASM_SCANEXCLUDE variable specifies the disks that are to be ignored.The variables take a whitespace-seperated list of prefix strings to match. In other words, if a disk starts with one of the prefix strings, it matches. For example, the prefix string sd will match all SCSI devices. The disk sda starts with sd. Note that these are not globs. They do not use wildcards. They are simple prefixes. Also note that the /dev/ path is not part of the prefix.

# ORACLEASM_SCANORDER: Matching patterns to order disk scanning

# ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan
