Cluster commands are used to monitor and modify clusters.
A cluster consists of up to four pairs of nodes that provide a
single configuration and service interface. There are a number of
cluster commands available for various tasks.
- addnode
- Adds a new (candidate) node to an existing cluster.
- cfgportip
- Assigns an IP address to each node ethernet port for iSCSI I/O.
- chcluster
- Modifies the attributes of an existing cluster.
- chclusterip
- Modifies the IP configuration parameters for the cluster.
- chiogrp
- Modifies the name of an I/O group or the amount of memory that
is available for Copy Services or VDisk mirroring.
- chnode
- Changes the name assigned to a node.
- cleardumps
- Cleans the various dump directories on a specified node.
- cpdumps
- Copies dump files from a nonconfiguration node onto the configuration
node.
- detectmdisk
- Rescans the fibre-channel network for new managed disks.
- ping
- Used to diagnose IP configuration problems by checking
whether the specified IP address is accessible from the configuration
node.
- rmnode
- Deletes a node from the cluster.
- rmportip
- Removes an iSCSI IP address from a node ethernet port.
- setclustertime
- Sets the time for the cluster.
- setpwdreset
- Changes the status of the password-reset feature for the display
panel.
- settimezone
- Sets the time zone for the cluster.
- startstats
- Starts the collection of per-node statistics
for virtual disks (VDisks), managed disks (MDisks), and nodes.
- stopcluster
- Shuts down a single node or the entire cluster.
- stopstats
- Stops the collection of per-node statistics
for virtual disks (VDisks), managed disks (MDisks), and nodes.
