▼ To Connect Data Hosts to a 2530 Array
1. Locate the host ports at the back of the controller tray (FIGURE 5-4).
2. Connect one end of the SAS cable to a host port on a controller module.
Host ports are numbered from left to right: host port 1, host port 2, and host
port 3.
3. Connect the other end of each SAS cable to a data host HBA.
4. Repeat these steps for each host-to-controller connection.
Relocation Cautions
Use the following guidelines when relocating trays or drives from one storage array
to another.
Caution – Potential data loss – Moving a storage array or array components that are
configured as part of a volume group can result in data loss. To prevent data loss,
always consult a Customer Support representative before relocating configured
drives, controller trays, or drive expansion trays.
