3.4 Booting multiple servers
To boot more than one server at a time, perform the following steps:
1. Log in to the administration server as
root
user.
2. Start the SFS CLI by entering the following command:
# sfsmgr
.
.
.
sfs>
3. Depending on how the servers were last shut down, boot the servers as follows:
• If you know that both servers in a server pair were shut down cleanly (that is, they were not
crashed or powered off at the same time), you can boot the servers at the same time, as shown
in the following example:
sfs> boot server south[3-8]
• If the servers in a server pair were not shut down cleanly, or you are unsure how they were shut
down, boot one server in the server pair first. Do not boot the second server in the pair until the
first server is running. For example, boot servers
south3
through
south8
as follows:
sfs> boot server south[3,5,7]
When these servers have booted, boot the remaining servers as follows:
sfs> boot server south[4,6,8]
3.5 Shutting down an Object Storage Server or the MDS server
The
shutdown server
command is used to shut down and turn off the power to the servers in the system.
The
shutdown server
command sends a command to the specified server telling it to shut down and
turn off its power. There is a default waiting period of 90 seconds. If the server has not shut down and turned
off its power after that time, the
shutdown server
command turns off the power to the server through the
iLO connection.
You can use the
wait
option to change the default waiting period of 90 seconds. If you specify a wait
period of
0
(zero) seconds, the command to shut down is not issued to the server at all; instead, the power
to the server is turned off immediately through the iLO connection.
WARNING! For your safety, never perform any maintenance on a ProLiant DL server in the HP SFS system
without first disconnecting the server’s power cord from the power outlet. This is because the power to the
servers in an HP SFS system is under the control of the software and the system may power on the servers
at any time.
Avoid using the
wait=0
option, because it powers off the server without attempting to perform an orderly
shutdown. However, the
wait=0
option is useful and appropriate when the server is hung or otherwise
unresponsive. If you shut down a server pair with the
wait=0
option, when you next reboot the server pair,
one of the servers resets the other. Although both servers eventually boot, the second server takes much
longer to do so than the first server. To avoid this problem, boot the servers in the pair separately, as
described in Section 3.4.
