# diskutil(8)

Administers quorum partitions in a cluster.

## NAME

diskutil - Administers quorum partitions in a cluster.

## SYNOPSIS

**diskutil** -I \| -p \| -t

## DESCRIPTION

The **diskutil** utility enables you to administer the quorum partitions in a cluster.

## OPTIONS

You can specify the following  **diskutil** options:

- **-I**

  Initializes the quorum partitions. The **-I** option deletes any cluster database and cluster state information from the quorum  partitions.  Therefore, only invoke **diskutil -I** when you want to initialize the quorum partitions as part of  the cluster software installation procedure.   Do not invoke **diskutil -I** on a running cluster.

- **-p**

  Displays a summary of the header data structure for the quorum partitions.  You can check if the quorum partitions are mapped to the same physical disk on both cluster systems by invoking **diskutil -p** on each system and ensuring that the output is identical.  If the output is not identical,  the quorum partitions may not be set up correctly.\

  For example:\

  \# **diskutil -p**\
   \----- Shared State Header ------\
   Magic# = 0x39119fcd\

   \--------------------------------

- **-t**

  Verifies that the cluster system can read information from the quorum partitions.  When you invoke  **diskutil -t**, the cluster system identifies the quorum partition devices and then attempts to read  information from both partitions.  The read is successful if the system determines that the  data is a valid set of initialized cluster state information. If the read is not successful, the quorum partitions may not be set up correctly.\

  For example:\

  \# **diskutil -t**\
   Successfully verified that the quorum partitions are accessible.

Note that other **diskutil** options are only for development, and should not be used.
