Linux 6.9 Oracle 12c ASM DiskGroup configuration process after adding disk 1. After storage allocates space (disk), linux recognizes disk (restarts os) after 2.multi path software identifies, by default produces a device, obtains wwid at / dev/mapper/mulitpathdevX.3.scsi_id and configures / etc/mul tipath.conf, sets multipath device name (e.g. asmdata21), and restarts multipath service 3.1 / sbin/scsi_id-g-u-d / dev/mapper/multipathdevX

Example: 36000d3100152080000000000000000d8

3.2 vi / etc/multipath.conf

Multipath {

Wwid 36000d3100152080000000000000000d8

Alias asmdata22

}

3.3 service multipathd restart4. Modify / etc/udev/rules.d/99-oracle-asmdevices.rules, configure asm device name, restart udev4.1 vi / etc/udev/rules.d/99-oracle-asmdevices.rules

# add lines

ENV {DM_NAME} = = "asmdata22", OWNER:= "grid", GROUP:= "asmadmin", MODE:= "660", SYMLINK+=" oraasm/oraasm-$env {DM_NAME} "

4.2 reload udev rules and start udev

/ sbin/udevadm control-- reload-rules

/ sbin/start_udev

Note: start_udev may cause switching between vip and scanip. For more information, please see [Linux environment RAC ASM causes Start_Udev to terminate monitoring when adding a disk from]
