Reinstalling a StoreEasy 1440 NAS

[M. N.]

I have 2 StoreEasy 1440 NAS based on Windows Server 2012.

They work fine by now.

I need to ensure I can resinstall them in case of possible problems.

I have a DVD whose title is "HP StoreEasy 1000/3000 Storage and HP 3PAR StoreServ File Controller - Windows Storage Server 2012 R2 Standsrd (2CPU/2VM) System Recovery DVD verskion SWX4.00.0a".

In case of need can I just boot from the DVD and reinstall from scratch my NAS?

Do I need any additional tool?

Is there any newer version available?

Where can I locate the up-to-date administrator's manual?

Regards

M.N.
