switches so that the RAID array is assigned loop ID 0, expansion unit 1 has loop ID
1, and expansion unit 2 has loop ID 2. The range of IDs assigned to the drives is
shown in
TABLE 4-6.
5. Prepare the plastic left ear cap for replacement by aligning the inside round
notches of the cap with the round cylindrical posts (ball studs) on the ear.
6. Push the top and bottom of the ear cap onto the ear, pressing in on the top side
toward the center of the array first.
7. Continue pushing the top and bottom of the ear cap onto the ear, pressing on the
side toward the outside of the array.
Do not use force when placing a cap on an ear.
8. Lift the bezel into position and press it onto the front of the chassis until it is
flush with the front.
9. Use the key to lock both bezel locks.
4.12 Connecting Ports to Hosts
In a default array configuration, channels 0, 1, 4, and 5 are host channels, so you can
directly connect an array to four host computers. SFP connectors are plugged into
channels 0 and 4 on the upper controller and channels 1 and 5 on the lower
controller for this purpose.
You can connect two additional host computers to channels 0 and 1 of a Sun
StorEdge 3511 FC array. To support six host computers, however, you need to insert
SFPs in the four unpopulated host ports. Except for some clustering configurations,
when you connect two hosts to channel 0 or channel 1 on a Sun StorEdge 3511 FC
array, you must use host filtering if you want to control host access in this
configuration. Refer to the user documentation for your clustering software to
determine whether the clustering software can manage host access in this
configuration.
