Migrating from RAID 0 to RAID 1 in an HP Smart Array

I have two disks in an HP Smart Array P410 and one disk is configured as a logicaldrive.

root@linux:~ # hpacucli ctrl all show config

Smart Array P410i in Slot 0 (Embedded) (sn: 5001438010849BE0)

array A (SAS, Unused Space: 0 MB)

logicaldrive 1 (279.4 GB, RAID 0, OK)

physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 300 GB, OK)

unassigned

physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 300 GB, OK)

In order to do that, I’ll add the drive to the logical drive using the command below. Note that I can’t using the current configuration.

root@linux:~ # hpacucli ctrl slot=0 ld 1 add drives=1I:1:3

Error: This operation is not supported with the current configuration. Use the
“show” command on devices to show additional details about the
configuration.

I also try to modify the RAID to RAID 1 in this logical drive.

root@linux:~ # hpacucli ctrl slot=0 ld 1 modify raid=1

Error: This operation is not supported with the current configuration. Use the
“show” command on devices to show additional details about the
configuration.

According to Smart Array P410i Controller Technical Specifications

The HP Smart Array P410 is an 8 Port Serial Attached SCSI (SAS) RAID controller. The P410 is designed for RAID applications and can be upgraded with the 512MB battery-backed write cache (BBWC) or 512MB / 1GB flash-backed write cache (FBWC) and the Smart Array Advanced Pack.

Management Features:
Online array expansion (with BBWC/FBWC upgrade)
Online Advanced Capacity Expansion (with BBWC/FBWC and Smart Array Advanced Pack upgrade)
Online logical drive extension (with BBWC/FBWC upgrade)
Online RAID level migration (with BBWC/FBWC upgrade)
Online strip size migration (with BBWC/FBWC upgrade)
Offline Mirror splitting and recombining (with BBWC/FBWC and Smart Array Advanced Pack upgrade)
Unlimited global online spare assignment
User selectable expand and rebuild priority
User selectable RAID level and stripe size
User selectable read and write cache sizes

That means that you must have the Battery-Based Write Cache  (BBWC) or Flash-Based Write Cache (FBWC) upgrade in order to do that.

To check if you have BBWC, run hpacucli ctrl all show config detail and verify if it shows Battery/Capacitor Count: 1
