Show the encryption state of zfcp-attached LUNs

Edit online

7.1 LPAR mode z/VM guest

lsluns -a shows the encryption state of the attached LUNs.

Note: Running lsluns -a causes extra SAN traffic for each attached LUN.

lsluns syntax

Filter the listing by specifying one or more FCP device bus-IDs, target port WWPNs, or both.


1 lsluns
1  -a? +   -c <device_bus_id>
2.1+ 
2.1  -p <wwpn>

Where:

-a or --active
shows the encryption state of the attached LUNs. Encrypted devices are indicated with a bracketed X immediately after the LUN number.
-c <device_bus_id> or --ccw=<device_bus_id>
filters LUNs by one or more adapters with the specified FCP device-bus IDs. When used in conjunction with −p, only those LUNs are listed that also satisfy at least one of the −p constraints.
-p <wwpn> or --port=<wwpn>
filters LUNs by one or more target ports with the specified WWPNs. When used in conjunction with −c, only those LUNs are listed that also satisfy at least one of the −c constraints.
-v or --version
displays version information and exits.
-h or --help
displays an overview of the syntax. To view the man page, enter man lsluns.

Examples

  • This example shows the encryption status of attached LUNs: 
    # lsluns -a
adapter = 0.0.3c02
     port = 0x500507630300c562
          lun = 0x401040a200000000(X) /dev/sg0    Disk	IBM:2107900
          lun = 0x401040a300000000    /dev/sg1    Disk	IBM:2107900
          ...
     port = 0x500507630303c562
          ...
adapter = 0.0.593a
          ...
    The (X) after the LUN number indicates that the device is encrypted.
