How Can I Configure the core dump Partition of ESXi Hosts in SAN Boot Scenarios?

How Can I Configure the core dump Partition of ESXi Hosts in SAN Boot Scenarios?

Question

How can I configure the core dump partition of ESXi hosts in SAN boot scenarios?

Answer

When core dump is triggered, the system saves the onsite information to a valid partition of a system disk on a host before the system breaks down. Only the latest onsite information is saved in the partition and all previous information is cleared. The valid partition is called core dump. ESXi hosts provide commands used to configure the core dump partition. In SAN boot scenarios, after an operating system is installed, a valid core dump partition has been automatically configured by default.

The method used to confirm and configure the core dump partition of ESXi hosts is as follows:
  1. Run the esxcfg-dumppart -l command to check whether the core dump partition is activated.
    ~ # esxcfg-dumppart -l
    VM Kernel Name                               Console Name                                               Is Active   Is Configured
    naa.674a063100f89a1e026196260000001f:7       /vmfs/devices/disks/naa.674a063100f89a1e026196260000001f:7 no          no          
    naa.674a063100f89a1e026196260000001f:9       /vmfs/devices/disks/naa.674a063100f89a1e026196260000001f:9 yes         yes  
  2. The following conditions exist:
    1. If no dump partition is configured, the values of all core dump partitions' Is Configured parameters are no. Run the esxcfg-dumppart -S command to configure and activate them.
    2. If the value of one core dump partition's Is Active parameter is yes, the core dump partition has been activated. You do not need to configure the core dump partition. If the values of all core dump partitions' Is Active parameters are no, no core dump partition is activated. Run the esxcfg-dumppart -a command to activate a core dump partition.
