Je me suis débrouillé tout seul comme un grand (nan j'déconne, j'ai réussi à trouver de l'aide sur un autre forum).
Solution :
Si vous utilisez Powerpath, il faut absolument effectuer la commande :
Code :
1
2
| echo "1" > /sys/class/scsi_device/3\:0\:0\:0/device/rescan
echo "1" > /sys/class/scsi_device/4\:0\:0\:0/device/rescan |
en adaptant au device qui va bien.
Ensuite, il vous suffit de suivre à la lettre ce qui est indiqué à l'
adresse
Je remets dans le code, ce qu'il contient au cas où la page serait supprimée :

There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
