To configure ASMLIB to exclude particular single path disks, complete the following procedure.
- Using a text editor, open the ASMLIB configuration file
- Edit the ORACLEASM_SCANEXCLUDE variable to provide the prefix path of the single path disks.
For example, if you want to exclude the single path disks
/dev/sdc, then provide a prefix path similar to the following:
- Save the file.
sdcprefixes, so that it ignores
/dev/sdc. It does not ignore other SCSI disks, nor multipath disks. If you have a multipath disk (for example,
/dev/multipatha), which accesses both
/dev/sdc, but you have configured ASMLIB to ignore
sdc, then ASMLIB ignores these disks and instead marks only the multipath disk as an Oracle ASM disk.
