Replacing an NVRAM adapter in an N7000 series system (Data ONTAP
8.1.x and earlier)
The NVRAM PCI adapter provides nonvolatile memory to your system and acts as
a memory buffer. It also serves as the interconnect adapter in an HA pair . To
replace the adapter, you must select the correct procedure for your system.
This procedure applies only to systems running
Data ONTAP
®
8.1.x
or earlier versions
About this task
v
This procedure is only for systems running Data ONTAP 8.1.x or earlier.
v
These procedures refer to HA pairs , which in releases prior to Data ONTAP 8.0
were called active/active configurations .
v
You must replace the failed component with a replacement FRU component you
received from your provider.
v
All other components in the system must be functioning properly; if not, you
must contact technical support.
v The term, system, refers to the IBM N series filer and gateway systems within
this platform family.
Replacing an NVRAM adapter in a system operating in 7-Mode
You must use a specific procedure to replace the adapter in a system operating in
7-Mode. Because the disk ownership ID is based on the NVRAM adapter serial
number, as the last part of the procedure you must reassign the system ID of the
new adapter to the disks attached to the system.
Noting the system ID (if it is a gateway system)
If you have a gateway system, first note the system ID from the system
configuration file.
Shutting down the target controller
You shut down or take over the target controller using different procedures,
depending on whether it is part of an HA pair or a stand-alone system.
Shutting down a node in an HA pair :
To shut down the node you must determine the status of the node and, if
necessary, take over the node so that the partner continues to serve data from the
node's storage.
Procedure
1. Check the status of the target node (the node you want to perform maintenance
on) by entering the following command at the system console of either node:
cf status
2. Take one of the following actions, depending on the result of the
cf status
command:
