How to use SAS (SAN) disks ?

[dpayet]

Hello,

i'm a little confused ... I have a server with SAS disk attached (not iSCSI). I "see" those disk in Proxmox in Datacenter/Storage : /dev/sdb & /dev/sdc with type "partitions". I have activated multipath and have a /dev/mapper/san.

First question : is it normal to view the 2 disks in Datacenter/Storage or should i see the /dev/mapper ?
Second : how use this disk when creating a VM ? I have the message "no disk available" (I have the message in French but it would be something like that).

I have tried to create a VG but no success (i see the LV in LVM but with 100% use).

I don't know where to go, if you have a lead ...

Thanks in advance and sorry for my english

you have to configure your SAN first.
create lun on SAN, configure multipath on proxmox side and then configure lvm on proxmox.....

Hello,

thanks for your replies. I figured out, I have re-create a PV and a VG and finally add the VG in the datacenter/Storage GUI config.
Works fine now
