New HDD not recognized in DSM 6.2-23739

[plaster]

hi guys, i've already posted this question but probably in the wrong section and now i've more information

the DSM 6.2-23739 with jun 1.03b loader running on an old supermicro 24bays with the adaptec 5805 (bios 5.2-0) 
xpenology running well and everything that i need works perfectly, but now i need more storage, actually there are only 2 hdd, the Ironwolf 4tb (ST4000VN008-2DR)in a storage pool and in rad1,  and i've bought two new Seagate IronWolf 4TB (ST4000VN006-3CW) but the xpenology in the storage manager after a lot of reboot not recognized it and only see the old 2 disks available

i've tried to go to bios and boot into adaptec bios and all 4 disks are seen, so the problem is not releated to hardware or cable

what can i try to do?

When you set up you drive, which raid type did you choose? SHR or Raid 1?

If Raid 1 you may need to change it to Raid 5 before the NAS will recognize the disks. Look here:

thanks for reply

1st i've already a raid1 with the old 2 hdd and there are important files in there, if i change raid i'll lost data?

2nd. ok could be that but its normal that i don't see in storage manager? i see only the two old ones

In the first line of the instructions it states you will not loose data:

 

Change the RAID Type of a Storage Pool

Storage pools can be changed from one RAID type to another without losing existing data. For example, you can create a RAID 1 storage pool on your Synology NAS and later change it to RAID 5 if you install more drives. This article provides instructions on changing the RAID type of existing storage pools on your Synology NAS.

ok you're right but till in the HDD/SSD Section my new hdd does not appear i can't change the raid because i can't choose that option and the problem for me is to visualize those disks

i've tried to log in with putty, maybe i'm wrong, but with fdisk -l in the end of list they see 1hdd of 3.7tb and my external hdd of 1.8tb
