Server Alarms
DUP (Duplication Manager)
The Duplication Manager process, via coordination of the Arbiter process, runs on the servers
to control data shadowing between them.
At the physical and data-link layers, an Ethernet-based duplication link provides a TCP
communication path between each server’s Duplication Manager to enable their control of data
shadowing. This TCP/IP link provides the actual data shadowing for software duplication. For
hardware duplication, there is an additional fiber optic link between the duplication memory
boards that provides the data shadowing.
Table 10: DUP Alarms describes the Duplication Manager’s alarms and their troubleshooting
procedures.
See ARB (Arbiter) and DAJ1/DAL1/DAL2 (Duplication Memory Board) for more information.

1 MAJ “Duplication card error” — The Duplication Manager determined that the
duplication card is not functioning, but it cannot distinguish between a bad
card, an unplugged card, or a bad fiber link.
Follow steps 1 - 7 if using the Web Interface. Follow steps 8 - 14 if using
the Linux command line interface.
1. Using the Web Interface: Check the physical fiber connectivity at
each server.
2. Verify the alarm by accessing the trace log by:
a. Selecting the View System Logs diagnostic and
Logmanager Debug trace
b. Specifying the Event Range for the appropriate time frame
c. Matching the “dup” pattern
3. Examine the trace-log query’s output for one of these messages:
“glbi: couldn't open Dup Card, errno=. ndm exiting”
“glbi: mmap failed, errno=. ndm exiting”
“Haven't heard from active dupmgr. Dup fiber link down.”
“san_check_rsp() FAILED: Dup Fiber link down.”
4. See if the dup link is both “up” and “refreshed” from the Web
interface’s Server section by selecting View Summary Status
5. If so, manually clear the alarm by selecting Alarms and Notification,
the appropriate alarm, and Clear
