Managing a cluster

Managing a cluster in takeover mode

Takeover mode differences from normal mode

The following subsections describe differences between managing a filer in normal mode and doing so in takeover mode.

Takeover mode prompt

In takeover mode, the prompt looks like this:

filer1(takeover)>

This indicates that filer1 is in takeover mode.

Statistics in takeover mode

In takeover mode, statistics for some commands differ from the statistics in normal mode in the following ways:

Each display reflects the sum of operations that take place on the takeover filer plus the operations on the emulated filer. Therefore, the display does not differentiate between the operations on the takeover filer and the operations on the emulated filer.
The statistics displayed by each of these commands are cumulative.
After giving back the failed partner's resources, the takeover filer does not subtract the statistics it performed on behalf of the failed filer in takeover mode.
The giveback does not reset (zero out) the statistics.
If you want accurate statistics from a command after a giveback, reset (zero out) the statistics as described in the man page for the command you are using.

Statistics are treated differently in takeover mode than in normal mode for the following commands:

httpstat

ifstat

netstat

nfsstat

sysstat

SNMP in takeover mode

You can have different settings on each filer for SNMP options, but any statistics gathered while a filer has been taken over do not distinguish between filers.
