Chapter 8 Maintaining Your Array 8-11
The Channel Status Table is displayed with the status of all channels on the array.
Note – Each controller has a separate RS232 port, as well as an Ethernet port. This
architecture ensures continuous communication should a controller fail. Since the
connection is established with only one controller (even when the array is in
redundant mode), the CurSyncClk and CurWid settings are displayed for the
connected controller. Therefore, if a user maps one LUN to the primary controller,
and another LUN to a secondary controller, only the LUN mapped with the
connected individual controller is displayed through the serial and Ethernet port
menu.
Caution – Do not change the PID and SID values of drive channels.
TABLE 8-5 Parameters Displayed in the Channel Status Table
Parameters Description
Chl Channel’s ID.
Mode Channel mode.
RCC Redundant controller communication channel.
Host The channel is functioning as a host channel.
DRV The channel is functioning as a drive channel.
DRV+RCC The channel is functioning as a drive channel with a
redundant controller communication channel.
PID Primary controller’s ID mapping:
* Multiple IDs were applied (host channel mode only).
# The ID to which host LUNs are mapped in the host channel
mode. ID for the primary controller in drive channel mode.
NA No ID applied.
