Shutting Down A Tuple - HP NetServer AA 4000 Administrator's Manual

Chapter 9

Shutting Down a Tuple

Before you shut down a tuple IOP, consider the fact that when a tuple is shut down, both the CE
and IOP are removed from service. As a result, any non-mirrored devices that physically reside
on that IOP are not available to the server. For this reason, you may decide to shut down the
tuple at another time.
To shut down a tuple:
Step Action
1 Follow the instructions in the procedure
Shutting Down the Server
2 Use Endurance Manager to ensure the
following:
• The IOP in the tuple you want to shut
down is not the source of a mirror copy
that has started or is pending.
• The other CE is active.
• The other IOP is active.
• The IOP in the other tuple has public
network connectivity (IOPx.Ethernet
cable is active and appears either light or
dark green in the Endurance Manager
Administration Window).
3 From Endurance Manager, issue the Tuple
Disable command for the tuple that you
want to shut down.
4 Do one of the following:
• Issue a Windows NT shutdown of the
IOP.
• Issue an Endurance Manager shutdown
of the IOP.
5 After shutdown completes on the IOP,
power off the IOP and CE in the tuple that
you disabled in step

step 3.
Notes
Do this only if you are willing to remove the server
from service. If you do not want to remove the
server from service, continue with the next step.
If possible, perform any necessary backups for non-
mirrored devices on the IOP that you want to shut
down.
Unless you take measures to prevent it, the CE and
IOP attempt to rejoin the server automatically.
