We'll create RAID10 of six drives (this is Logical Drive).
But first, let's add Global Spare Drive, which is spare for any logical drive in the storage.
Well in this case we have only one logical drive, so it will also work creating Local Spare Drive, which in case of more logical drives is spare one only for specific logic drive.
Anyway, remember, this is just example for learning and reference.
Okay, we have Global Spare drive.
Let's add Logical drive as I said before.
Go to 'View and Edit Logical Drives'
The system has FC drives.
Select RAID 1.
Select remaining six drives to form RAID 1.
Note: in the list there is no RAID 10, which is mirroring and striping.
But if you use 4 and more disks for RAID1, the final result will be RAID10.
It is important to know that it must be even number of disks, not odd number.
Escape will show additional info.
New escape will ask to confirm creation of logical drive.
And wait for initialization.
Now we have logical drive.
Logical drive can be partitioned.
StorEdge 3510 also supports Logical Volumes, which is collection of two or more Logical drives. Since we have only one Logical drive, we are not using Logical Volumes.
Still here is some tips about logical volumes:
1. For FC, logical volume can have max 32 partitions.
2. Host sees partition of logical volume as one single physical disk.
About Channels.
Channels 0 and 1 are for host connection.
Channels 2 and 3 are to connect other 3510 as extensions (drive channels).
Channels 4 and 5 are for host connection but possibly can be used as drive channels.
At this point, we cannot really use this storage:
Select LUN 0 - logical drive - partition 0
Map host LUN
And we see some different results:
