Replacing an expansion canister
This topic describes how to replace an expansion canister.
Attention: If your system is powered on and performing I/O operations, go to
the management GUI and follow the fix procedures. Performing the replacement
actions without the assistance of the fix procedures can result in loss of data or
access to data.
Even though many of these procedures are hot-swappable, these procedures are
intended to be used only when your system is not up and running and performing
I/O operations. Unless your system is offline, go to the management GUI and
follow the fix procedures.
Be careful when you are replacing the hardware components that are located in the
back of the system that you do not inadvertently disturb or remove any cables that
you are not instructed to remove.
Be aware of the following canister LED states:
v If the power LED is on, do not remove an expansion canister unless directed to
do so by a service procedure.
v If the power LED is flashing or off, it is safe to remove an expansion canister.
However, do not remove an expansion canister unless directed to do so by a
service procedure.
Attention: Even if an expansion canister is powered off, it is still possible to lose
data. Do not remove an expansion canister unless directed to do so by a service
procedure.
To replace an expansion canister, perform the following steps:
1. Read the safety information to which "Preparing to remove and replace parts"
on page 209 refers.
2. Record which SAS cables are plugged into the specific ports of the expansion
canister. The cables must be inserted back into the same ports after the
replacement is complete; otherwise, the system cannot function properly.
3. Disconnect the SAS cables for each canister.
4. Grasp the handle between the thumb and forefinger.
Note: Ensure that you are opening the correct handle. The handle locations
for the node canisters and expansion canisters are slightly different.
Handles for the upper and lower expansion canisters overlap each other. The
handle with the finger grip on the left removes the upper canister ( 1 ). The
handle with the finger grip on the right removes the lower canister ( 2 ).
