MSA 2040 13TB LUN is Recognized 11.82TB in ESXi 6.7
Hello everybody
I think the topic clearly states my problem.
9 * 1.8 TB Disks are RAID-5ed together So a total space of ~14.4 TB is available. I created a 13 TB LUN in this linear disk group (which is shown as 12.9 TB in MSA SMU). So far so good. But all my hosts which are ESXi 6.7 only detect 11.82 TB of this storage. Here are snapshots of MSA and ESXi
Any help would be appreciated.
Regards

This is likely a TB (Base 10) vs TiB (Base 2) “loss”
All HDD vendors present their disk capacities in Base 10. Most file systems present their disk capacities in Base 2.
On the MSA, change the default “base preference” to base 2 under "User Management"
Hope this helps!

Hi, Exactly the correct answer.
Now I should calculate why a 9*1.8T RAID 5 only gives me 10.9 TiB ;)
Even if a 1.8 disk is about 1650GB

I would request you to provide me the below outputs,
show cli-parameters
show disks
show vdisks
show volumes
Otherwise you can share MSA log (store.logs) file in private chat with me. Never share MSA log in public forum.
Hope this helps!
