【RAC】節點2上不能完全識別節點1上的asmdisk

ASM
當主節點安裝oracleasm disk
[root@rac1 dev]# /etc/init.d/oracleasm deletedisk /dev/sdc1 VOL01

[root@rac1 dev]# /etc/init.d/oracleasm scandisks

VOL101
VOL102
VOL103
VOL104
VOL201
VOL202
VOL203
VOL204
在第二節點上檢視的時候發現有一部分卷組沒有識別，fdisk -l 是可以識別到的！
[root@rac2 dev]# /etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks:               [  OK  ]
[root@rac2 dev]# /etc/init.d/oracleasm listdisks
VOL101
VOL102
VOL103
VOL104---缺少 VOL201 VOL202 兩塊卷組！
VOL203
VOL204

由於是vmware ESX 安裝共享儲存，檢視配置檔案：
[root@rac shared_storage]# ll

[root@rac shared_storage]# 
發現第二個節點的vmx配置檔案
scsi1:3.present = "TRUE"
scsi1:3.fileName = "/vmfs/volumes/4adc51a2-4dbc89c1-55f4-00221957b3b8/shared_storage/share5.vmdk"
scsi1:3.mode = "independent-persistent"
scsi1:3.deviceType = "scsi-hardDisk"

scsi1:4.present = "TRUE"
scsi1:4.fileName = "/vmfs/volumes/4adc51a2-4dbc89c1-55f4-00221957b3b8/shared_storage/share5.vmdk"
scsi1:4.mode = "independent-persistent"
scsi1:4.deviceType = "scsi-hardDisk"
修改scsi1:3.fileName 的為share4.vmdk
scsi1:3.present = "TRUE"
scsi1:3.fileName = "/vmfs/volumes/4adc51a2-4dbc89c1-55f4-00221957b3b8/shared_storage/share4.vmdk"
scsi1:3.mode = "independent-persistent"
scsi1:3.deviceType = "scsi-hardDisk"
注意：上述修改第二節點的配置檔案的操作必須在第二節點主機關閉的情況下執行，重啟之後，再次檢查！！
[root@rac2 ~]# /etc/init.d/oracleasm scandisks

[root@rac2 ~]# 
成功。。
