Removing A Control Module - Dell EqualLogic PS6010 Hardware Maintenance

PS6010 Hardware Maintenance
You can partially or completely remove a control module without shutting down
the array if the remaining control module has at least one connected and
functioning network interface. However, if you remove the active control module
(the LED labeled ACT will be green), there will be a short interruption as failover
to the secondary control module occurs.
Otherwise, if possible, cleanly shut down the array before removing the module,
as described in Shutting Down and Restarting an Array on page 1-6.
Caution: Do not remove a control module from an array while the control
modules are still synchronizing. A message will appear on the
console when synchronization completes. The ACT LED on the
secondary control module will be orange when synchronization
completes.

Removing a Control Module

Before removing a control module:
• Attach an electrostatic wrist strap, as described in Using an Electrostatic Wrist
Strap on page 1-5.
• Disconnect any serial or network cables attached to the control module.
Optionally, re-attach the network cables to the other control module to
provide uninterrupted data access.
To remove a control module:
1. Open the control module latches by squeezing together the release mechanism
for each latch and then rotating each latch outwards.This will disengage the
control module from the array. See Figure 3-2.
