Rebooting an IOP
Before you reboot an IOP, consider the following points which may affect your decision to
reboot the IOP at that time.
• When an IOP is removed from service (powered off, disabled, faulted or booted in any
mode other than Operational Endurance I/O Processor Mode):
- Any non-mirrored devices that physically reside on that IOP are not available to the
server.
- The keyboard and mouse attached to that IOP are not available to the CE operating
system.
• As an alternative to removing an IOP from service, consider scheduling an appropriate
maintenance time (the same day) when you can remove the server from service. Then, use
the procedure Rebooting the Server to avoid remirroring all mirrored disk sets.
To reboot an IOP:
Step Action Notes
1 Follow the instructions in the procedure
Rebooting the Server on page 214.
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.
2 Use Endurance Manager to ensure the
following:
• That the IOP you want to reboot is not
marked as the source of a mirror copy.
• That the other IOP is active.
• That the other IOP has public network
connectivity (IOPx.Ethernet cable is
online).
If possible, perform any necessary backups for non-
mirrored devices on the IOP that you want to reboot.
3 Reboot the IOP using either of the
following methods:
• From Endurance Manager, issue the
command IOPx Shutdown.
• From the local IOP:
a.Make sure that the keyboard and
mouse are controlling the IOP’s
operating system.
b.Issue a Windows NT Shutdown
command.
If necessary, enter the hotkey sequence to switch
control to the IOP’s operating system.
