Shutting Down an IOP Before you shut down an IOP, consider the following points. You may decide to shut down the IOP at another 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 Endurance server. - If the CE operating system will be restarted while the IOP is removed from service, you must reboot the CE again after the IOP is again online in order for non-mirrored devices connected to the IOP to come online. - The keyboard and mouse attached to that IOP are not available to the CE operating system. - Redirected video from the CE operating system is not available for display on this IOP. • As an alternative to removing an IOP from service, consider scheduling an appropriate maintenance time (the same day) when you can remove the Endurance server from service. Then, use the procedure Shutting Down the Endurance Server to avoid remirroring all mirrored disk sets. Endurance Server Maintenance 9-5

Endurance Server Maintenance
9-5
Shutting Down an IOP
Before you shut down an IOP, consider the following points. You may decide to shut down the
IOP at another 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
Endurance server.
-
If the CE operating system will be restarted while the IOP is removed from service,
you must reboot the CE again after the IOP is again online in order for non-mirrored
devices connected to the IOP to come online.
-
The keyboard and mouse attached to that IOP are not available to the CE operating
system.
-
Redirected video from the CE operating system is not available for display on this
IOP.
°
As an alternative to removing an IOP from service, consider scheduling an appropriate
maintenance time (the same day) when you can remove the Endurance server from
service. Then, use the procedure
Shutting Down the Endurance Server
to avoid
remirroring all mirrored disk sets.
