6. Repeat step 1 through step 5 for each host channel that you intend to use.
Step 5 – Connecting the controller to a drive enclosure
The steps in this procedure describe how to attach Fibre Channel cables to a drive enclosure. The steps
for connecting other types of drive enclosure cables are similar, but they do not require the installation of
SFP transceivers.
1. If there is a black plastic plug in the drive port of the new controller CRU/FRU, remove it.
2. Insert an SFP transceiver into the drive port on a controller CRU/FRU.
3. Plug one end of the cable into the SFP transceiver.
4. Plug the other end of the cable into the appropriate in port or out port on the environmental services
module (ESM) in the drive enclosure as applicable for your cabling configuration.
5. Attach a label to each end of the cable by using this scheme. A label is very important if you need to
disconnect the cables later to service a controller.
— The controller ID (for example, controller A)
— The drive channel number and port ID (for example, drive channel 1, port 2)
— The ESM ID (for example, ESM A)
— The ESM port ID (for example, In, Out, 1A, or 1B)
— The drive enclosure IDExample label abbreviation – Assume that a cable is connected between
drive channel 1, port 2 of controller A to the out port of the left ESM (A) in drive enclosure 1. A label
abbreviation could be as follows:
CtA-Dch1/P2, Dm1-ESM_A (left), Out
6. Repeat step 1 through step 5 for each drive enclosure.
7. Remove the anti-static protection.
Step 6 – Running diagnostics
1. Using the LEDs on the storage subsystem and information provided by the storage management
software, check the status of all enclosures in the storage subsystem.
2. Does any component have a Needs Attention status?
— Yes – Click the Recovery Guru toolbar button in the Subsystem Management Window, and
complete the recovery procedure. If a problem is still indicated, contact your Technical Support
representative.
— No – Go to step 3.
3. Create, save, and print a new storage subsystem profile.
