Re: How do I expand a Raid 6- R720


I am assuming below requirements are met in your server to perform capacity expansion:

  • Created RAID disk might have left with free capacity, in this case size can be expanded to maximum available free size.
  • There are free disks available and connected to H710P controller. Which are of same Protocol (SAS/SATA), sector(512e/4k) as per the configured disks for RAID6 and size of these drives are of same or larger capacity than lowest drive used for RAID6 creation.

In order to perform capacity expansion, Pre boot interfaces such as CTRL_R or UEFI of H710P can be used by providing free capacity drives or expanding to remaining free capacity without adding any new disks.

In order to perform capacity expansion in OS environment, tools such as OM can be used for expansion. Please refer below link for OM installation in ESXi host.
