Replacing a Fibre Cable or Hub
Use the following steps in “Remove a Fibre Cable or Hub” and “Install
a Fibre Cable or Hub” to replace a cable connected to either side of
your hub or to replace the hub itself.
Remove a Fibre Cable or Hub
Use the following steps to remove a cable connected to either side of
your hub or to remove the hub itself:
1. Shut down the host system.
2. Shut down the controllers. In single-controller configurations, shut
down “this controller.” In dual-redundant controller configurations, shut
down the “other controller” first, then shut down “this controller” with
the following commands:
SHUTDOWN OTHER_CONTROLLER
SHUTDOWN THIS_CONTROLLER
When the controllers shut down, their reset buttons and their first three
LEDs are lit continuously. This may take several minutes, depending on
the amount of data that needs to be flushed from the cache modules.
3. If you are replacing a cable, unplug the failed cable at each end. If you
are replacing a hub, unplug all of the cables connected to the hub.
Install a Fibre Cable or Hub
Use the following steps to install a cable connected to either side of
your hub or to install the hub itself:
1. If you are replacing a cable, plug the replacement cable into the ports
that the removed cable was plugged into.
If you are replacing a hub, plug all of the cables that were unplugged
from the removed hub into the replacement hub.
2. Push both reset buttons to restart the controllers.
The controllers automatically restart. Your subsystem is now ready for
operation.
