san storage in proxmox

[shiblovich]

hi all ,
I have proxmox server , this server connected to san storage to get 11TB ,
my problem is he read 4 disks with same storage , for example
#lsblk
sdb 8:16 0 12T 0 disk
└─sdb1 8:17 0 12T 0 part
sdc 8:32 0 12T 0 disk
└─sdc1 8:33 0 12T 0 part
sdd 8:48 0 12T 0 disk
└─sdd1 8:49 0 12T 0 part
sde 8:64 0 12T 0 disk
└─sde1 8:65 0 12T 0 part

also

root@proxmox1:~# /lib/udev/scsi_id -g -u -d /dev/sdb1
360002ac0000000000000001e0000d16b
root@proxmox1:~# /lib/udev/scsi_id -g -u -d /dev/sdc1
360002ac0000000000000001e0000d16b
root@proxmox1:~# /lib/udev/scsi_id -g -u -d /dev/sdd1
360002ac0000000000000001e0000d16b
root@proxmox1:~# /lib/udev/scsi_id -g -u -d /dev/sde1
360002ac0000000000000001e0000d16b

thanks in advance .

The key search words that you need are:
debian multipath

You can start reading here: https://pve.proxmox.com/wiki/ISCSI_Multipath, just mostly ignore references to iSCSI. In general the net is full of wonderful information on setting up Multipath. If you add to the search your SAN model, you may even find specific information for it.

Here is another thread about it, if you're unsure how to proceed. Just use a simple configuration file with your one lun to start with. Best to ask your SAN vendor for specific settings for the configuration file, often they have settings for you. Report back if there are (more) problems.
