Managing filers in takeover mode

Takeover mode tasks

You can do the following tasks in takeover mode:

Administer the local filer as you would any normal filer. Take into account the minor differences between a filer in normal mode and a filer in takeover mode described in the next section,"Takeover mode differences from normal mode."
Enter partner mode and administer the virtual filer, as described in "Managing a virtual filer."
Initiate or force a giveback, as described in "Performing a giveback."

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

Statistics are treated differently in the following commands:

httpstat

ifstat

netstat

nfsstat

sysstat

In takeover mode, statistics for the preceding 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 virtual filer. Therefore, the display does not differentiate between the operations on the takeover filer and the operations on the virtual 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.

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 does not distinguish between filers.
