520 IBM System Storage DS6000 Series: Copy Services with IBM System z
SNMP overview
The DS8000 sends out SNMP traps when a state change in a remote copy services
environment occurs. Therefore, 13 traps are implemented. The traps 1xx are sent out for a
state change of a physical link connection, and the 2xx traps are sent out for state changes in
the logical copy services setup.
The DS HMC can be set up to send SNMP traps to up to 2 defined IP addresses.
eRCMF
(see Chapter 30, “IIBM TotalStorage Rapid Data Recovery” on page 457) is listening to
SNMP traps for the DS6000. Also, a Network Management program, such as Tivoli Netview,
can be used to catch and process the SNMP traps.
Physical connection events
With the trap 1xx range, a state change of the physical links is reported. The trap is sent out if
the physical remote copy link is interrupted. The link trap is sent from the primary system. The
PLink and SLink columns are only used by the Enterprise Storage Server (ESS).
If one or several links (but not all links) are interrupted, a trap 100, as shown in Example B-1,
is posted; it indicates that the redundancy is degraded. The RC
column in the trap represents
the reason code for the interruption of the link. The reason codes are listed in Table B-1 on
page 521.
Example: B-1 Trap 100: PPRC links degraded

2: FIBRE 0103 XXXXXX 0002 XXXXXX 17
If all links are interrupted, a trap 101, as shown in Example B-2, is posted. This event
indicates that communication between primary and secondary system is no longer possible.
Example: B-2 Trap 101: PPRC links down
PPRC Links Down

1: FIBRE 0003 XXXXXX 0003 XXXXXX 17
2: FIBRE 0103 XXXXXX 0002 XXXXXX 17
When the DS6000 can communicate again by any of the links, trap 102, as shown in
Example B-3, is sent after one or more of the interrupted links are available again.
Example: B-3 Trap 102: PPRC links up
