DL380 G7 - W2K8 R2 Server - How to convert Array from RAID0 to RAID1 set

DL380 G7 Proliant, with Smart Array P410i Controller with 256mb. 

Array A = Raid0 - 1 x 146GB

Unassigned Disk = 1 x 146GB

 

How do I go about adding the unassigned disk to Array A and creating a RAID1 set?  The only Wizard options present within HP Array Configuration Utiltiy are: Express Configuration/ Controller Settings/ Add a Logical Drive (which only allows me to create a brand new Array) / Remove a logical drive & More Information.

 

I've also booted server from HP SmartStart - again no obvious options on how to add disk.

 

Any ideas would be greatly appreciated.

hi,

 

You need BBWC to expand/extend the array. Those options will appear in ACU, when you add the battery.

First you need to ensure that both Cache+battery is installed for this controller (BBWC). If there no Cache and battery, then you cannot do Expansion, extension and migration.

 

As per my understanding, HP Dos not really recommended RAID 0 to any other RAID migration but you can do it (I have done it)

 

Steps to follow: (You need to perform below said steps under Configuration tab of ACU

 

Select the RAID 0 Array (not logical drive),then click on Expand Array button

Select the new unassigned HDD and Expand Array

Wait till the expansion/Transformation is complete.

Now select the RAID 0 logical drive (Not Array) from ACU

Click on Migrate RAID/Stripe Size

Now you will get an option RAID 1.

Wait till Migration is completed.

Hi

 

THanks for the prompt reply, from searching HP docs thought that i would have to have Battery cache alright, but was hoping there was a way around this! 

 

Kind Regards,

Edel.
