Hello,

Is there any command in the Linux CLI that shows the LUN identifier (LUN WWN/Volume Serial) of the Huawei OceanStor array? Without using the ultrapath driver.


Something similar to AIX command lsmpio.


server:/root # > lsmpio -ql hdisk211

Device:  hdisk211

          Vendor Id:  HUAWEI

         Product Id:  XSG1

           Revision:  4303

           Capacity:  70.00GiB

      Volume Serial:  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX  (Page 83 NAA)


Thank you

Dear,

Run the multipath -ll command to verify that the configuration has taken effect.

[root@localhost ~]# multipath -ll mpathaf (361603041002d0306003e6dc300000009) dm-9 HUAWEI  ,XSG1             size=5.0G features='0' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=1 status=active   |- 2:0:2:4 sde  8:64   active ready running   |- 9:0:2:4 sdq  65:0   active ready running   |- 2:0:3:4 sdaw 67:0   active ready running   |- 9:0:3:4 sdas 66:192 active ready running   |- 2:0:0:4 sdi  8:128  active ready running   |- 9:0:0:4 sdak 66:64  active ready running   |- 2:0:1:4 sdo  8:224  active ready running   `- 9:0:1:4 sdao 66:128 active ready running mpathae (361603041002d0306003e549f00000000) dm-3 HUAWEI  ,XSG1             size=50G features='0' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=1 status=active   |- 2:0:2:1 sdb  8:16   active ready running   |- 9:0:2:1 sdm  8:192  active ready running   |- 2:0:3:1 sdat 66:208 active ready running   |- 9:0:3:1 sdap 66:144 active ready running   |- 2:0:0:1 sdf  8:80   active ready running   |- 9:0:0:1 sdah 66:16  active ready running   |- 2:0:1:1 sdj  8:144  active ready running   `- 9:0:1:1 sdal 66:80  active ready running

In the command output, the two mapped LUNs have been taken over by the OS native multipathing software and all paths are active, indicating that the configuration has taken effect.

Dear,

The show lun general command is used to query information about LUNs in the storage system.

For example:

admin:/>show lun general 

  ID  Name     Pool ID  Capacity  Health Status  Running Status  Type  WWN                               Is Add To Lun Group  Smart Cache Partition ID  DIF Switch  Is Clone  Subscribed Capacity Function Type

  --  -------  -------  --------  -------------  --------------  ----  --------------------------------  -------------------  ------------------------  ----------  --------  ------------------- -------------

  0   snap     0        10.000GB  Normal         Online          Thin  6cf02031000405060049949200000000  No                   --                        No          No        8.129GB             Lun

Hope this can help you, thank you.

No, that's not what I'm asking. I need to know how to find out the LUN WWN/Volume Serial on the Linux host side in CLI.
