Determining the Type of Logical Volume

Paging space logical volumes will generally hold the system dump. However, because an incomplete dump may not be usable, follow the procedure below to make sure that you have enough dump space.

  1. Enter the sysdumpdev command to list the dump devices. The logical volume of the primary dump device might be /dev/lg_dumplv or /dev/hd7.
    Note: You can also determine the dump devices using SMIT. Select the Show Current Dump Devices option from the System Dump SMIT menu.
  2. Determine your logical volume type by using SMIT. Enter the SMIT fast path smit lvm or smitty lvm. You will go directly to Logical Volumes. Select the List all Logical Volumes by Volume Group option.

    Find your dump volume in the list and note its Type (in the second column). For example, the logical volume type might be sysdump if the dump device is lg_dumplv, or paging if the dump device is hd6.
