Endurance Server Maintenance 9-7
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 Endurance server. For this reason, you may decide to shut
down the tuple at another time.
To shut down a tuple:
Step Action Notes
1 Follow the instructions in the procedure
Shutting Down the Endurance Server
on page 9-9.
Do this only if you are willing to remove the
Endurance server from service. If you do not
want to remove the Endurance server from
service, continue with the next step.
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).
If possible, perform any necessary backups for
non-mirrored devices on the IOP that you want
to shut down.
3 From Endurance Manager, issue the
command
Tuple Shutdown
Operation from IOPn
for the tuple
that you want to shut down.
Refer to page 5-84 for detailed information
about the command
Tuple Shutdown
Operation from IOPn
.
4 After shutdown completes on the IOP,
power off the IOP and CE in the tuple
that you disabled in step 3.
Unless you take measures to prevent it, the CE
and IOP attempt to rejoin the server
automatically.
