Smart Array P410 change the Raid

Kavatch — Wed, 07 Feb 2018 06:27:41 GMT

Hey,

I have a HP ProLiant SE316M1 with a Smart Array P410 Raid controler.

I have checked the raid type with "cciss_vol_status /dev/sdb" and the output was:

/dev/sda: (Smart Array P410) RAID 5 Volume 0 status: OK.
/dev/sdb: (Smart Array P410) RAID 5 Volume 1 status: OK.

I noticed the type was RAID 5. Now I want to change the RAID to RAID 1. What is the best way to do that?

Ps: Here is the output for "hpacucli ctrl all show detail"

Hi,

I really don't think there is online option for migrating from RAID 5 to RAID 1 for P410 controller. This feature is available only with new generation controllers.

You need to do it manually. Take a back up from RAID 5. Delete the RAID and then Create a new RAID 1 and bring back all the data.

Hi,

As per the Description, I understand that you would like to change the configuration from RAID 5 to RAID 1.

I would recommend you to afford for a downtime and load into Offline ACU Utility.

Link: https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_3c888073127c4c65b7bd8559eb

Once the ACU Utility is loaded, you need to select the Logical drive for which the configuration needs to be changed.

On the Right hand side there will be an option of Migrate RAID.

Please click on it and you will see all the Possible Options available.

Regards.
