Repair Information
For a description of the Element Manager Logs and an explanation of the button
functions at the bottom of the log window, refer to the hp StorageWorks Director
Element Manager User Guide.
Three logs are accessed through the EWS interface:
164
Director 2/140 Event Log—Displays a history of events for the director,
such as system events, degraded operation, FRU failures, FRU removals and
replacements, port problems, Fibre Channel link incidents, and HAFM
appliance-to-director communication problems. All detected software and
hardware failures are recorded in the Director 2/140 Event Log. The
information is useful to maintenance personnel for fault isolation and repair
verification.
Hardware Log—Displays a history of FRU removals and replacements
(insertions) for the director. The information is useful to maintenance
personnel for fault isolation and repair verification.
Link Incident Log—Displays a history of Fibre Channel link incidents (with
associated port numbers) for the director. The information is useful to
maintenance personnel for isolating port problems (particularly expansion
port [E_Port] segmentation problems) and repair verification.
Threshold Alert Log—Displays details of the threshold alert notifications.
Besides the date and time that the alert occurred, the log also displays details
about the alert as configured through the Configure Threshold Alert(s)
option under the Configure menu.
Open Trunking Log—Displays the average data rates of all traffic flows on
ISLs (from a receive port to a target domain). Open Trunking also
periodically adjusts routing tables to reroute data flows from congested links
to lightly loaded links and optimizes bandwidth use. The objective of Open
Trunking is to make the most efficient possible use of redundant ISLs
between neighboring switches, even if these ISLs have different bandwidths.
EWS Event Log—Displays events or errors recorded at the EWS interface.
Entries reflect the status of the interface and managed director. The log stores
up to 200 entries, and the most recent entry appears at the top of the log.
EWS Open Trunking Re-Route Log—Displays interswitch link (ISL)
congestion events that cause Fibre Channel traffic to be routed through an
alternate ISL. Entries reflect the traffic re-route status at the managed director.
EWS Link Incident Log—Displays Fibre Channel link incident events
recorded at the EWS interface. Entries reflect the cause of the link incident.
