The -rdrivecount field is important and is limited to the following values:  VNX OE for Block v31 ================ RAID 5: 5 RAID 6: 8 RAID 1/0: 8  VNX OE for Block v32 ================ RAID 5: 5, 9 RAID 6: 8, 16 RAID 1/0: 8  I can actually tell from the error message you received, that you are running VNX OE for Block v32:  [...] Unsupported RAID drive count. The following values are supported for RAID 5: 5, 9 [...]   If you were to compare the list above to the Unisphere interface, you would see that they match exactly the "RAID Type" pull down where it defines both the RAID Type and the size of the underlying private RAID Groups the system will (try to) create.   Keep in mind, that if you do want the private RAID Groups to be anything other than the given choices, then the right strategy would not be to provide all 32 drives as you have in your original command.  If you were to follow the logic explained in the following post and provided -rdrivecount 9 (you wouldn't be able to get the desired R5 (7+1) with -rdrivecount 5):  [URL]#696115  Then ran the following commands:  1) navisecccli -help  IMPORTANT: Verify that you are running at least naviseccli Revision 7.32+   2) navisecccli -h storagepool -list -listinternal   This will list the private RAID Groups associated with each pool.   3) navisecccli -h getrg -<engineering password>  You can then get the number of drives associated with the pRG's that you listed from the previous command.   You would see that it created the following underlying private RAID Group structures which you wouldn't want.  Again, this is if you were to run your original command providing all 32 drives:  3x R5 (8+1) 1x R5 (4+1)   Instead as explained in the post referenced above, the proper strategy if you insist on R5 (7+1) pRG structures would be instead to:  1) Create initial tier with 8 drives (selecting: -rdrivecount 9) 2) Expand tier with 8 drives at a time  EDIT: updated to cleanup formatting
Hi! It's possible to create RAID 5 (6+1) pool on VNX5300 system? If possible, how i can do this? I can't find information about this in official documents. Maybe i can create RAID 5 (6+1) over navisphere cli?
