If the ARX has a redundant peer, copy the running-config off of the peer, too. You do
not need to copy the global-config, which is shared between the peers. For example,
The Non-Volatile RAM (NVRAM) memory contains namespace metadata
information that managed volumes are currently using. If this memory is lost, all
managed volumes must re-import all of their back-end shares. To protect against this
time-consuming process, the NVRAM chip has a separate battery backup that lasts up
to 72 hours.
Before you shut down any services, use the
the battery is in good working order. The output must indicate that the battery is in a
"Good" state and that the Error-Correction Circuitry (ECC) indicates that the
NVRAM has "No Error." Run this on both peers if you have redundancy configured.
For example, this output indicates that the "bstnA6k" chassis has a battery that is
ready for power-off:
bstnA6k# show chassis nvr

This example shows that the redundant peer, "bstnA6kB," also has a fully-charged
battery:
