Replacing Controller Canisters in the E5660 Controller-Drive Tray to Update HICs - 3
ATTENTION Possible data loss
– If you continue with the steps to replace a controller while I/O operations
are occurring between the storage array and attached hosts, you might lose data.
6. On each host that is connected to the storage array, unmount all file systems associated with volumes on the
storage array.
7. Wait for five minutes.
8. In the
Hardware
tab of the
AMW
, select the graphic representation of the storage array, and then select
Monitor
>
Reports
>
Operations in Progress
to make sure that there are no background operations in
progress.
The
Operations in Progress
window shows the time remaining for any operations. Wait for those operations to
complete before you continue with the next step.
9. Turn off power to the controller-drive tray.
10.Wait for all of the LEDs on the controller-drive tray to go dark.
11.Turn off power to each drive tray that is connected to the controller-drive tray.
12.Wait for two minutes for all of the drives to spin down.
Removing the Controller Canisters from the E5660 Controller-Drive Tray
ATTENTION Possible hardware damage
– To prevent electrostatic discharge damage to the tray, use proper
antistatic protection when handling tray components.
1. Put on antistatic protection.
ATTENTION Potential degraded performance
– To prevent degraded performance, do not twist, fold, pinch,
or step on the cables. Many cables have a minimum bending radius. Check the specifications for your cables,
and do not bend any cable tighter than the minimum specified radius.
2. Label each of the interface cables and Ethernet cables attached to the controller canisters. Depending on your
new HIC configuration, you might be able to reconnect some cables after you replace the controller canister.
3. Disconnect all of the interface cables and Ethernet cables from the controller canisters.
4. If the old controller canister contains a Fibre Channel HIC or an InfiniBand HIC, remove the small form-factor
pluggable (SFP+) transceivers (for Fibre Channel) or quad SFP (QSFP+) transceivers (for InfiniBand) from the
HIC and save them for possible reuse.
5. Remove controller A.
NOTE
The following figures show the controller in the bottom position within the controller-drive tray. However,
you might be removing the controller from the top position. The required actions are similar.
a. Unlock and pull out the release levers to release the controller canister.
