Switch Infrastructure Diagnostics
165
Keep in mind how long link aggregation has been configured and how much load the system has been under. If link
aggregation was just configured very recently, and there has not been much data load on the system, then the data
reported may not provide you with applicable information. Make sure the system has been under load, and then run
Diagnostics again to capture a new load balancing report.
Also, if one of the link aggregated port members has been down previously, then keep in mind that the data
transmitted and received on this port will always be less than other group members (depending on how long this link
was down). The data reported is a total of all packets sent and received on this port since the last time Switch
Diagnostics was run.
The next time Diagnostics is run, the load balancing values will be cleared, so Download the Diagnostics results
before running Diagnostics again in order for Avid Personnel to better analyze the situation.
Counters
Counters and Registers
When reviewing this data, keep in mind the last time these values were reset. Counters and incrementing Register
values get reset every time the switch reboots or Diagnostics is run.
n
Some Register values under the “Registers” column cannot be cleared by Switch Diagnostics. These values can only
be reset by rebooting the switch.
If the switch has been running for several months without running Diagnostics, then some of these values may get
quite high, and still mean the system is healthy. Or, a spike of packet drops may have occurred several weeks in the
past – so the values reported are high, but the network may have since cleared up. If values reported by Diagnostics
seem suspect, and the system is still under data load, then try waiting a few minutes and run Diagnostics again. If the
test still flags WARN or FAILED for values reported, then contact Avid Personnel for additional help.
n
The time to wait depends on how much system load is traveling through the switches, network configuration, how
many clients are connected, etc.
Remember that the next time Diagnostics is run, the counter and register values will be cleared, so download the
Diagnostics results before running Diagnostics again in order for Avid Personnel to better analyze the situation.
Connectivity
Default Gateway
If the gateway cannot be reached by ping, check the following:
• Is the gateway up and running?
• If there are switches between the storage system and the gateway, verify that every switch is running
successfully and properly configured to allow communication to the gateway from the storage system.
• If there are switches between the storage system and the gateway, verify that the 10G link between the storage
system and the switch has link (Port Link Information test) and is not dropping packets (Counters and
Registers).
Ping Storage Blades
If a Storage Blade is not reachable by ping, make sure that the Storage Blade is not pulled out of its slot. If the
Storage Blade appears to be seated, try reseating it. If the Storage Blade is still unreachable, try moving it to a
different slot. If the LED lights up on the Storage Blade, then also check the Intermittent Link test for a possible
intermittent link, and Counters and Registers for error statistics.
