The ORACLEASM_SCANORDER variable specifies disks to be scanned first.
The ASMLIB configuration file is located in the path
/etc/sysconfig/oracleasm. It contains all the startup configuration you specified with the command
/etc/init.d/oracleasm configure. That command cannot configure scan ordering.
The configuration file contains many configuration variables. The ORACLEASM_SCANEXCLUDE variable specifies the disks that are to be ignored.
Configure values for ORACLEASM_SCANORDER using space-delimited prefix strings. A prefix string is the common string associated with a type of disk. For example, if you use the prefix string
sd, then this string matches all SCSI devices, including
/dev/sdc and so on. Note that these are not globs. They do not use wild cards. They are simple prefixes. Also note that the path is not a part of the prefix. For example, the
/dev/ path is not part of the prefix for SCSI disks that are in the path
For Oracle Linux and Red Hat Enterprise Linux version 5, when scanning, the kernel sees the devices as
/dev/mapper/XXX entries. By default, the device file naming scheme udev creates the
/dev/mapper/XXX names for human readability. Any configuration using ORACLEASM_SCANORDER should use the
