Start NSD

The Start NSD DMP assists to start NSDs that are not working.

The following are the corresponding event details and the proposed solution:
  • Event ID: disk_down
  • Problem: The availability of an NSD is changed to “down”.
  • Solution: Recover the NSD.

The DMP provides the option to start the NSDs that are not functioning. If multiple NSDs are down, you can select whether to recover only one NSD or all of them.

The system issues the mmchdisk command to recover NSDs as given in the following format: 
/usr/lpp/mmfs/bin/mmchdisk <device> start -d <disk description>

For example: /usr/lpp/mmfs/bin/mmchdisk r1_FS start -d G1_r1_FS_data_0
