Viewing system information 4–2
4.1 Viewing server information
The
show server
command provides information on the state of servers. If you suspect that one or more
of the servers is not functioning correctly, you can use this command to determine which servers are running,
and what services they are providing.
The server states are described in Table 4-1.
To view the status of all servers in the system, enter the
show server
command as shown in the following
example:
sfs> show server
Name State Power Services
-------- -------------- -------- ----------
south1 running on admin mds1
south2 power-off off none
south3 running on ost1 ost2 ost3 ost4
south4 down on none
In this example, the output provides the following information:
• The power to the MDS server (
south2
) is turned off, and the MDS service (
mds1
) has failed over to
the administration server.
• The administration server (
south1
) is serving both the administration and the MDS services.
• One of the Object Storage Servers (
south4
) is down. However, the power to the server is still on; this
indicates that the server has hung or is in the process of being shut down.
• The OST services from
south4
are being served by
south3
. (These servers are configured as a
server pair, with shared access to storage).
Table 4-1 Server states
State Description
booting
The power to the server has just been turned on, and the server is booting. This is a
temporary state. If the server does not respond after three minutes, it will be marked with
the status
down
.
disabled
The server is disabled and no services are running on the server. To enable the server,
shut it down, enter the
enable server server_name
command, and then boot the
server.
down
The server has shut down, or is not responding, or has ceased to be a member of the
system.
not-configured
• The server has not completed the configuration process, or
• A system parameter has been changed for a previously configured server.
If certain system parameters (such as the Start IP address of an interconnect) are
changed, the servers are using an actual configuration that differs from the parameters
in the database. To indicate this, the system changes the state on each server to
not-configured
. See Section 4.1.1 for more information.
(You can use the
show server server_name
command to determine the
configuration status of a server.
not-responding
The server is not responding. This is a temporary state, and the state usually changes to
down
(or, in some exceptional cases, to
running
) within a short time.
power-off
The power to the server is turned off.
running
The server has completed the booting process, is a member of the system, and is running
normally.
unknown
This is a temporary state that only occurs immediately after the monitoring daemon
(
hplsmond
) is started. The state soon changes to one of the other states.
