Metadata server does not start and no master disk is found in the standard log

This topic explains how to identify when lost LUNs are preventing the metadata server from starting correctly.

Context

This can occur in situations such as a recent complete power failure, and when the metadata LUNs were not available at the time that the metadata server started. If you attempt to start the metadata server using the startserver command, and the metadata server does not start:

Steps

  1. View log.std to determine the cause of the problem.
  2. Search for a message that reads, "No master disk found." If you find that message, continue with step 3. Otherwise, this is not the problem.
  3. Search for a message that begins, "Tank.Bootstrap file does not match...". If you find the message, continue with step 4. Otherwise, this is not the problem.
  4. Make sure that you have Subsystem Device Driver installed on the metadata server.
  5. Run the lsvpcfg command to determine if you have the required LUNs. If no LUNs are listed, or the list is incomplete, continue with step 6.
  6. Restart the system to find any available storage LUNs.
  7. Contact your support representative if the LUNs are still not available.
