No it doesn't work.

setting quota for id=10097 dev=/dev/scsi/host1/bus0/target0/lun0/part7
setquota: Bad block softlimit: /dev/scsi/host1/bus0/target0/lun0/part7
setquota: Usage:
  setquota [-u|-g] [-F quotaformat] <user|group>
        <block-softlimit> <block-hardlimit> <inode-softlimit> 
<inode-hardlimit> -a|<filesystem>...

My system_quota (xfshome) file looks as follow.

fs = /dev/scsi/host1/bus0/target0/lun0/part7
0           409600  409600     512     512
fs = /dev/scsi/host1/bus0/target0/lun0/part7
10098       409600  409600     512     512
fs = /dev/scsi/host1/bus0/target0/lun0/part7
10000       409600  409600     512     512
...
