Connecting an appliance to more than one storage shelf
The steps in this section assume that the appliance and the storage shelves are shipped together and installed at the same time. You can install up to six storage shelves with a 5270 appliance.
You can add storage shelves to an operational appliance. Refer to one of the following appendices for instructions.
Appendix A - Adding one or more storage shelves to an operating appliance that does not have any storage shelves
Appendix B - Adding storage shelves to an operating appliance that has at least one storage shelf attached
See Overview.
Note:
Be sure that you orient the blue tabs on each SAS-3 connector correctly. Refer to the following section for details.
Warning:
The hardware must be powered on in the expected order. Else, all the storage may not be seen by the appliance.
To connect an appliance to storage shelves
Note:
This section provides detailed instructions to connect four storage shelves to an appliance. Instructions for connecting six shelves are provided where necessary.
- Connect the cables as follows:
Connect the appliance external RAID controller left port to port A on the top canister of the storage shelf.
Connect each storage shelf top canister port B to next storage shelf top canister port A.
Connect the appliance external RAID card right port to the last storage shelf bottom canister port A.
Note:
In a six-shelf configuration you must connect the appliance RAID card right port to port A in the bottom canister of the sixth storage shelf.
Starting with the last storage shelf, connect the storage shelf bottom canister port B to the next storage shelf bottom canister port A.
Connect another cable to the shelf that is second from the bottom. Use port B on the lower canister of that shelf.
Connect the other end of the cable to the shelf that is third from the bottom. Use port A on the lower canister of that shelf.
Continue until the all storage shelf bottom canisters are connected.
- In a two-shelf configuration, verify that all cables are installed as shown.
- In a three-shelf configuration, verify that all cables are installed as shown.
- In a four-shelf configuration, verify that all cables are installed as shown.
- In a five-shelf configuration, verify that all cables are installed as shown.
