Examples

  1. To list components sorted by name, enter the following command:
    $ mmlscomp --sort name

    The system displays output similar to this:

        Rack Components
 
Comp ID  Part Number  Serial Number  Name
-------  -----------  -------------  ------
      9  1410HEA                     R01C01
 
    Storage Enclosure Components
 
Comp ID  Part Number  Serial Number  Name                Display ID
-------  -----------  -------------  ------------------  ----------
      2  1818-80E     SV12345007     G1E1-SX98760044     01
      4  1818-80E     SV12345005     G1E2-SX98760049     05
      3  1818-80E     SV12345003     G1E3-SX98760041     13
      7  1818-80E     SV12345008     G1E4-SX98760036     17
      1  1818-80E     SV12345001     G1E5-SX98760048     21
      6  1818-80E     SV12345002     G1E6-SX98760050     25
      8  1818-80E     SV12345006     G1E7-SX98760039     33
      5  1818-80E     SV12345004     G1E8-SX98760052     37
  2. To list components in stanza format, enter the following command:
    mmlscomp --format stanza

    The system displays output similar to this:

    %rack:
  compId=9
  name=R01C01
  partNumber=1410HEA
 
%storageEnclosure:
  compId=1
  displayId=21
  name='1818-80E-SV12345001'
  partNumber=1818-80E
  serialNumber=SV12345001
 
%storageEnclosure:
  compId=2
  displayId=1
  name='1818-80E-SV12345007'
  partNumber=1818-80E
  serialNumber=SV12345007
 
%storageEnclosure:
  compId=3
  displayId=13
  name='G1E3-SX98760044'
  partNumber=1818-80E
  serialNumber=SV12345003
