Description
If you run this command from an engine hosting a subordinate metadata
server, this command displays only the following information:
- Name of the cluster.
- IP address of the master metadata server.
- Cluster port number of the master metadata server.
- Heartbeat port number of the master metadata server.
- Client-metadata server port number of the master metadata server.
- Administrative port number of the master metadata server.
If
you run this command from the engine hosting
the master metadata server and you do not specify a parameter, this command
displays the following default information:
- Name of the cluster.
- ID of the cluster.
- Current state of the cluster. See Cluster states for a description for possible values.
- Target state to which the cluster is switching.
- Timestamp of the last current state change.
- Timestamp of the last state change.
- Number of metadata servers in the cluster.
- Number of metadata servers that are actively participating in the cluster
(in the offline, online, or quiescent state).
- Committed software version - the currently installed
version of the software.
- Software version - the version of the software at which
the cluster is currently operating.
- Timestamp when the latest software was committed.
- Software commit status (In Progress or Not In Progress).
- Timestamp of the last installation.
- Progress of an active metadata check, expressed in terms
of 0 to 100 percent. A dash (-) indicates that there is not a metadata check
in progress.
If
you run this command from the engine hosting
the master metadata server and you specify the
–netconfig parameter,
this command displays the following information in addition to the default
information:
- Name of the master metadata server.
- IP address.
- Cluster port number.
- Heartbeat port number.
- Client-metadata server port number.
- Administrative port number.
If
you run this command from the engine hosting
the master metadata server and you specify the
–workstats parameter,
this command displays the following information in addition to the default
information:
- Number of system-update transactions involving the creation, modification,
and deletion of system objects.
- Number of system-object transactions, involving the creation, modification,
and deletion of objects. The system objects include storage pools, filesets,
volumes, policies, and engines.
- Current number of buffers, which are used for system metadata activity,
that contain data but are available for reuse (clean buffers).
- Current number of buffers, which are used for system metadata activity,
that contain data awaiting I/O to disk (dirty buffers).
- Current number of buffers, which are used for system metadata activity,
that are not in use (free buffers).
- Current total number of buffers for system metadata activity.
If
you run this command from the engine hosting
the master metadata server and you specify the
–config parameter,
this command displays the following information in addition to the default
information:
- Pool-space reclamation interval, in minutes.
- List of clients with root or administrative privileges.
- Remote Supervisory Adapter (RSA) user ID.
- RSA password. The password appears as asterisks, with one asterisk per
character in the password.
- Size, in 4-KB pages, of the master metadata server buffer.
- Size, in pages, of the subordinate metadata server buffer.
- Administrative process limit.
- Metadata server workload process limit.
If
you run this command from the engine hosting
the master metadata server and you specify the
–advconfig parameter,
this command displays the following information in addition to the default
information:
- Maximum number of missed network heartbeats before a metadata server detects that it has
lost communication with another metadata server in the cluster. When a metadata
server detects this situation, it logs the occurrence in the cluster log and
attempts to recover from the fault. The value can be from 1 to 100. The default
value is 40.
- Network heartbeat interval, in milliseconds for periodic
pings among metadata servers in
the cluster. The value can be from 200 to 10 000. The default value is 500.
- Cluster timeout, in milliseconds.
- Maximum number of retries to client. This is the maximum
number of times a send can be attempted from the metadata server to
the client before declaring the client's session lease to be expired. The
value can be from 1 to 100. The default value is 5.
- Client timeout, in milliseconds.
- Client lease period, in seconds. This is the amount of
time that a SAN File System internal lock is leased to a client when the metadata server grants a lock. The
defined value is 20. This value may be adjusted only by service representatives.
- Client-lease-period multiplier. This multiplier accommodates
possible networking delays between the time a message gets sent from the client
until it is received by the metadata server. The defined value is 2. This
value may be adjusted only by service representatives.
- Metadata server timeout, in milliseconds.
- Maximum number of missed disk heartbeats before the metadata server is dropped from the
cluster. The value can be from 1 to 100. The default value is 4.
- Disk heartbeats interval, in milliseconds, for periodic
pings among metadata servers in
the cluster. The value can be from 200 to 10 000. The default value is 500.
- Available languages.
- Current languages.
