Figure 5-29 Error code 1625 Fix Procedure - Problem fixed
5.3.3 Monitoring Performance menu
IBM Flex System V7000 Storage Node has a Performance menu that gives a first impression
of how the system is performing. The performance chart is split into four sections:
CPU Utilization - subdivided into:
– CPU time used for the system
– CPU time used to handle compression
Interfaces - subdivided into:
– FC - Fibre Channel traffic towards hosts
– iSCSI - shows iSCSI traffic towards hosts
– SAS - traffic towards the disk back-end
Volumes - traffic towards hosts that has mapped volumes - subdivided into:
– Reads in MegaByte per second (MBps)
– Writes in MegaByte per second (MBps)
– Red latency in milli seconds (ms)
– Write latency in milli seconds (ms)
Note: The error 1625 in the preceding example occurred because one of our Control
Enclosure controllers had been temporarily removed from the system.
Figure 5-29 shows that a few more errors remain as unresolved. They should be fixed
similarly to the one we resolved in the previous example.
