[SunHELP] Reconfiguring an A1000

[Daniel Nuno]

Hello,

Your plan looks good to me, but I think you should also consider a DR plan,
because your downtime will be on friday and for some hours, so if you have
any problem, will be a little bit difficult to get support or spare parts.

Between step 5 and 6, you should consider creating the new file systems.

And depending on the amount of information and your stripe size is the time
of the restore.

Later, could be interesting for you to consider the firmware update:

E450
RaidManager
HBA
A1000
Hard disks

My suggestion would be to start step by step on the firmware update, don't
do too many changes at the same time.

Don't forget to run an explorer and keep it safe. To extract a module
profile from rm6 could be a good idea as well.

Regards,
Alejandro
