Replacing LRC modules with ESH2 modules in a disk shelf
Replacing LRC modules with ESH2 modules in a disk shelf
About replacing the
modules
You can convert a FAS270/FAS270c system using disk shelves with LRC
modules to one with disk shelves using ESH2 modules. You can convert a
FAS270c system by hot-swapping the LRC with ESH2 modules; that is, by
allowing the system to continue running without powering off. A FAS270
system, however, has a single loop, requiring that you take the system offline
before converting the modules.
Caution
If you attempt to hot-swap the LRC module with an ESH2 module on a disk shelf
that does not have multipath connections, you lose all access to the drives on that
disk shelf as well as those connected below it.
Replacing the
modules
To replace the LRC modules with ESH2 modules, complete the following steps.
Step
Action
1
Verify that your NetApp appliance meets the minimum software
requirements to support the disk shelf and module combination. See
the System Configuration Guide at

Then…
FAS270 system

Select which node/loop you want to
convert first; A or B. For the sake of
clarity, the following steps convert
node/loop B.

Result:
Takeover of node B is enabled on node A.
