【RAC】節點2上不能完全識别節點1上的asmdisk

當主節點安裝oracleasm disk

[root@rac1 dev]# /etc/init.d/oracleasm <b>deletedisk</b> /dev/sdc1 VOL01

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

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

VOL104

<b>VOL201</b>

<b>VOL202</b>

在第二節點上檢視的時候發現有一部分卷組沒有識别，fdisk -l 是可以識别到的！

[root@rac2 dev]# /etc/init.d/oracleasm scandisks

[root@rac2 dev]# /etc/init.d/oracleasm listdisks

VOL104---<b>缺少 VOL201 VOL202 兩塊卷組！</b>

[root@rac2 dev]# 

[root@rac2 dev]# fdisk -l

發現第二個節點的vmx配置檔案

scsi1:3.present = "TRUE"

<b>scsi1:3.fileName = "/vmfs/volumes/4adc51a2-4dbc89c1-55f4-00221957b3b8/shared_storage/share5.vmdk"</b>

scsi1:3.mode = "independent-persistent"

scsi1:3.deviceType = "scsi-hardDisk"

scsi1:4.present = "TRUE"

<b>scsi1:4.fileName = "/vmfs/volumes/4adc51a2-4dbc89c1-55f4-00221957b3b8/shared_storage/share5.vmd</b>k"

scsi1:4.mode = "independent-persistent"

scsi1:4.deviceType = "scsi-hardDisk"

<b>修改scsi1:3.fileName 的為share4.vmdk</b>

scsi1:3.fileName = "/vmfs/volumes/4adc51a2-4dbc89c1-55f4-00221957b3b8/shared_storage/share4.vmdk"

<b>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，重新開機之後，再次檢查！！</b>

[root@rac2 ~]# /etc/init.d/oracleasm scandisks

[root@rac2 ~]# /etc/init.d/oracleasm listdisks

成功。。
