RENAME/DELETE DISKLABEL through ASMLIB
We can rename a DISKLABEL in asm through two ways
1) RENAMING BY PROVIDING DISKLABEL NAME
In the below example, we are rename a disk label by providing the CURRENT DISKLABEL name to NEW DISKLABEL name
[[email protected]]# /etc/init.d/oracleasm force-renamedisk TEMP5 TEMP6
Renaming disk “TEMP5” to “TEMP6”: [ OK ]
[[email protected]]# oracleasm querydisk /dev/mapper/VOTE_05
Device “/dev/mapper/VOTE_05” is marked an ASM disk with the label “TEMP6”
2) RENAMING BY PROVIDING THE DISK
In the below example, we are rename a disk label by providing the disk and new name to be allocated for the disk
[[email protected]]# /etc/init.d/oracleasm force-renamedisk /dev/mapper/VOTE_05 TEMP5
Renaming disk “/dev/mapper/VOTE_05” to “TEMP5”: [ OK ]
[[email protected]]# oracleasm querydisk /dev/mapper/VOTE_05
Device “/dev/mapper/VOTE_05” is marked an ASM disk with the label “TEMP5”
We can DELETE a DISKLABEL in asm through two ways
1) DELETE ASM DISK LABEL BY PROVIDING DISKLABEL NAME
In below example we are check the disk to find the DISKLABEL and we are deleting a disklabel by providing the disklabel name
[[email protected]]# oracleasm querydisk /dev/mapper/VOTE_05
Device “/dev/mapper/VOTE_05” is marked an ASM disk with the label “TEMP5”
[[email protected]]# oracleasm deletedisk TEMP5
Clearing disk header: done
Dropping disk: done
2) DELETE ASM DISK LABEL BY PROVIDING THE DISK
In below example, we are deleting a disklabel by providing the disk and we are check the disk status after deleting the disklabel
[[email protected]]# oracleasm deletedisk /dev/mapper/VOTE_05
Clearing disk header: done
Dropping disk: done
[[email protected]]# oracleasm querydisk /dev/mapper/VOTE_05
Device “/dev/mapper/VOTE_05” is not marked as an ASM disk
