- How to create virtual disk in eHBA mode
Enhanced HBA mode (eHBA mode) is a new operating mode available with H740P, H745, and H745P MX cards. eHBA provides the following features:
- Create virtual disks with RAID level 0, 1, or 10.
- Present Non-RAID disks to the host.
- Configure a default cache policy for virtual disks. The starting default is write-back with read ahead.
- Configure virtual disks and Non-RAID disks as valid boot devices.
- Automatically convert all unconfigured disks to Non-RAID:
On system boot
On controller reset
When unconfigured disks are hot-inserted
- Please upgrade the PERC firmware to 50.5.0.1750 or later.
- Non-RAID disk is not supported in RAID mode, eHBA mode support both RAID and Non-RAID disk. (Supported RAID level: RAID 0, 1, or 10)
- All steps are completed in the System Setup page.
- Please clear all existing configuration on the controller before proceeding.
Caution: The data will be lost if clear all existing configuration, please backup the data in advance.
