External SAS disks with multipath - Different disknames in console and GUI?!

[Fazy]

Hy!

I've found some strange thing going with mpath SAS disks.

The setup:

It's an old HP stuff (includes one DL380 G6 and a JBOD with dual SAS ports)
CPU: 2 * Intel(R) Xeon(R) CPU E5520
Memory: 48G
SAS Card:
vendor = 'Broadcom / LSI'
device = 'SAS1068E PCI-Express Fusion-MPT SAS'
class = mass storage
subclass = SCSI
I'am bootin with HP RAID card from two local SAS, and also have a RAID1 with this conroller (I'know this not the best setup, I've just started to build this, and will change it in the future)

My TrueNAS version: (downloaded 2 days before): TrueNAS-12.0-U2.1

So in console, I've got the 12 disks on SAS bus:

Code:

root@truenas[~]# gmultipath status
            Name   Status  Components
 multipath/disk1  OPTIMAL  da25 (ACTIVE)
                           da23 (PASSIVE)
 multipath/disk4  OPTIMAL  da24 (ACTIVE)
                           da22 (PASSIVE)
multipath/disk12  OPTIMAL  da21 (ACTIVE)
                           da11 (PASSIVE)
multipath/disk11  OPTIMAL  da20 (ACTIVE)
                           da10 (PASSIVE)
multipath/disk10  OPTIMAL  da19 (ACTIVE)
                           da9 (PASSIVE)
 multipath/disk9  OPTIMAL  da18 (PASSIVE)
                           da8 (ACTIVE)
 multipath/disk8  OPTIMAL  da17 (ACTIVE)
                           da7 (PASSIVE)
 multipath/disk7  OPTIMAL  da16 (ACTIVE)
                           da6 (PASSIVE)
 multipath/disk6  OPTIMAL  da15 (ACTIVE)
                           da5 (PASSIVE)
 multipath/disk5  OPTIMAL  da14 (ACTIVE)
                           da4 (PASSIVE)
 multipath/disk3  OPTIMAL  da13 (ACTIVE)
                           da3 (PASSIVE)
 multipath/disk2  OPTIMAL  da12 (ACTIVE)
                           da2 (PASSIVE)

When I want to create my "Test" pool, (2 vdevs, 5-5 raidz2 disks + 2 spare) I cannod do that.

GUI:
- In Storage/Multipath, i see the same as in console
- As you can see in test_zpool_disks.PNG, there is 11 disk in the pool (the disk9 is missing, which came from da8 and da18, based on multipath informations)

And this is where my problem begins... If I want to add the 12th disk (disk9) as spare device, I not see it (I see the second SAS raid1, and I see a device da13)
However this da13 is the active path of disk3... (which is in the pool)

The Disks menu is also strange:
If you check the da13_pool_NA.PNG, you can see, this not attached (but it is!)
If you check the da18_testpool.PNG, you can see, that this da18 is attached to the Test pool

What am I missing?

Thanks:
Peter

Follow up: I've went to the SAS HBA BIOS, and there was some kind of clear function, which I used.
After that, I was able to add the disk9 (it's appeared on the list)

The da13 displaying issue however still exists...
