Legend:

  • Ok: The command ends normally and the task is performed.
  • Np: The command is not rejected and ends normally but the task is not performed.
  • Ab: The command is rejected and ends abnormally.

Do not specify noread mode (-m noread) for S-VOLs using RAID Manager. If you do, the command ends normally but the noread mode does not take effect.

If a RAID Manager command is rejected and ends abnormally and the host is running the HP-UX operating system, sense bytes (SSB) are output to the RAID Manager error log file. Sense bytes indicate the cause of the error.
