檢視伺服器上總共有多少個asmdisk
[root@GI_Softwareonly_64 ~]# oracleasm listdisks
OCPDATA1
OCPDATA2

檢視伺服器上總共有多少個asmdisk
[oracle@GI_Softwareonly_64 dbs]$ asmcmd lsdsk --discovery
Path
/dev/oracleasm/disks/OCPDATA1
/dev/oracleasm/disks/OCPDATA2

檢視伺服器上總共有多少個asmdisk，以及每個asmdisk的具體資訊(以下結果為兩行，分別對應OCPDATA1、OCPDATA2，含每個磁碟的可用空間，原始空間等)
[oracle@GI_Softwareonly_64 dbs]$ asmcmd lsdsk -k -t --discovery

檢視已經在asmdiskgroup中的asmdisk
[oracle@GI_Softwareonly_64 dbs]$ asmcmd lsdsk
Path
/dev/oracleasm/disks/OCPDATA1

檢視沒有在asmdiskgroup的asmdisk(即沒有被使用的asmdisk)
[oracle@GI_Softwareonly_64 dbs]$ asmcmd lsdsk --candidate
Path
/dev/oracleasm/disks/OCPDATA2

檢視asmdiskgroup的資訊(磁碟組的可用空間等)
[oracle@GI_Softwareonly_64 dbs]$ asmcmd lsdg --discovery -g

asmcmd lsdsk和lsdg檢視asmdisk和asmdiskgroup
