HP Surestore Disk Array 12h and FC60 - Manual (Page 176)

176 Configuration Switches
Configuration Switches
This section describes the configuration switches on the controller enclosure and the disk
enclosures. Configuration switch settings must be set to support the configuration (full-bus
ore split-bus) being installed (as planned for from chapter 2, Topology and Array Planning).
Controller enclosure and the disk enclosures configuration switches include:
– Disk enclosure (Tray) ID switches
– Disk enclosure DIP switches
– Controller enclosure Fibre Channel host ID address switches
Tips for Setting Configuration Switches
• All switch settings should be the same on both BCC modules on the disk enclosures.
• Disk enclosures must be power cycled before the new switch setting will take effect.
• If a BCC is installed that has settings different than its peer, a buzzer will sound. The
settings must be corrected to use the disk enclosure.
Disk Enclosure (Tray) ID Switch
The disk enclosure ID switch sets the Enclosure ID (or Tray ID). This value is used by FC60
diagnostic software and the controller to identify the disk enclosure for status monitoring
operations. Each enclosure in the array must be set to a different Enclosure ID. To set the
ID, set the rotary ID switches on the back of both BCC modules to the same number. See
Figure 64 . Typically, the disk enclosure closest to the controller enclosure is set to “0”, the
next one down to “1”, and so on down the rack. See "Selecting Disks for a RAID 0/1 LUN"
on page 243 for additional disk module addressing information.)
Disk Enclosure DIP Switch
A DIP switch located on the back of each BCC is used to set configuration options for BCC
operation. See
Figure 64 . These DIP switches contain five switch segments. Switch
segment 1 is used to select either split-bus or full-bus operation. See "Full-Bus/Split-Bus
(Switch 1) Configuration" on page 178 . The remaining four switch segments are not used
for disk array operation and must always be set to “0.”
