RAID 10 Listed as Not Supported When Creating RAID Volume With raidconfig (22129034)
On a system with the Sun Storage 6 Gb/s SAS PCIe HBA (internal or external), attempting to create a RAID 10 volume using raidconfig
with the --level=10
option will yield the following message: "ERROR: RAID level not supported by controller."
Workaround
The FCODE version 1.00.65 on the Sun Storage 6 Gb/s SAS PCIe HBA (internal or external) does not support RAID 10. It does support an even (four or more) or odd (3 or more) number of disks used in a RAID level 1e. Use RAID level 1e in place of RAID level 10.
For example, to create a RAID 1e volume on four disks in the system, type:
raidconfig create raid --level=1e -d c0d0,c0d1,c0d2,c0d3
This RAID volume will be seen as RAID 1e by raidconfig
, but seen as RAID 10 by the HBA's configuration utility (sas2ircu).
This is expected behavior with the Sun Storage 6 Gb/s SAS PCIe HBA using FCODE version 1.00.65.
