Oracle 在asm前使用udev繫結共享儲存

1. 在root使用者下使用fdisk -l 查詢主機上的盤，此次給主機分配了4塊2T左右的盤，由於多路徑的影響看到了8塊盤，可以不用管，用其中4塊就行。
# fdisk -l | grep Disk

2. 編輯/etc/udev/rules.d/99-oracle-asmdevices.rules檔案
# more 99-oracle-asmdevices.rules 
#ASM_DISKS
KERNEL=="sddlma[a-d]", OWNER="grid", GROUP="asmadmin", MODE="0660"

3. 重啟udev
/sbin/start_dev

4. 檢視繫結後的共享儲存
[root@DC8VFJNK2-R730 dev]# ls -l  sddlmaa
brw-rw---- 1 grid asmadmin 251, 0 Oct 12 15:37 sddlmaa
[root@DC8VFJNK2-R730 dev]# ls -l  sddlmab
brw-rw---- 1 grid asmadmin 251, 16 Oct 12 15:37 sddlmab
[root@DC8VFJNK2-R730 dev]# ls -l  sddlmac
brw-rw---- 1 grid asmadmin 251, 32 Oct 12 15:37 sddlmac
[root@DC8VFJNK2-R730 dev]# ls -l  sddlmad
