Processing dumps

Edit online

You can copy and transfer the dump file to another system, reduce the dump size, and send the reduced dump to IBM® Support.

Procedure

  • For LPAR dumps on DASD, tape, or a SCSI or NVMe disk, use the zgetdump command to copy the dump and transfer it to another system, see The zgetdump tool.
    With kdump, you can transmit the dump through a network. Use existing mechanisms to prevent conflicts when concurrently writing multiple dumps to a shared persistent storage space.
  • To analyze the dump, you can use crash, see The crash tool.
  • To receive a VMDUMP file, use the vmur command, see The vmur tool
