Y-A-T-Il Une Limite De Connexion En Iscsi

[netgus]

Bonjour à tous,

J'ai configuré 3 ESXI v5.1 sur mon Syno. J'ai installé l'adaptater iSCSI de VMWare. J'ai pu configurer les deux premiers serveur sans aucun problème, mais avec le dernier, je rencontre un problème de connexion.

Depuis le iSCSI Software Adapter, j'arrive à voir mes target, mais après validation, il lance le scan, mais rien ne monte.

Quel est le moyen pour moi de voir où est le problème ?

J'ai bien regardé les logs du Syno, mais je dois avouer que j'ai un peu de mal à les interpréter.

Un point étrange au niveau du statut du service, c'est les connexions établies. Je m'explique:

J'ai 3 serveurs avec pour chacun d'eux 2 portgroups (Syno1 et Syno2) en round robin. Ça, ça fonctionne sans aucun problème pour les deux premiers. Mais, dans le Syno, je peux voir 3 connexions par serveur sauf pour le troisième où je vois que les deux connexions de mes PortGroups.

Comme je n'ai aucun message d'erreur sur l'ESXI, je me suis dit que peut-être il y avait une limitation quelque part.

Bon, je ne suis pas un spécialiste du sujet, alors si quelqu'un a une petite idée du PB.

J'ai trouvé d'où venait mon problème.

- J'ai simplement augmenté le MTU de mon switch

- Les datastore ne montent pas sur de l'etherchannel.

- J'ai mis en place un Round Robin pour pallier à l'etherchannel

- Et il semblerait que mon Syno soit bloqué à 5 connexions en iSCSI et j'ai ouvrir un call afin de me le faire confirmer

Utilise la commande cat /etc/synoinfo.conf|grep iscsi pour consulter les limitations iSCSI.
Par exemple, un DS411+II supporte 32 cibles et 256 LUNs :

DiskStation> cat /etc/synoinfo.conf|grep iscsi
support_iscsi_target_block="yes"
iscsi_target_type="lio"
max_iscsiluns="256"
max_iscsitrgs="32"
support_iscsi_target="yes"
support_iscsi_lunbkp="yes"
DiskStation>
