    SCSI reset error on a cluster 2 nodes connected to a jbod 3310 storage

    807557
      Dear Gents,

      I will detail the environment which which the customer face the problem in. then i will till you what the problem he face:


      1- he has 2 clustered servers which are connected to a 3310 JBOD storage (no controller), the 2 connections come through 2 different SCSI Cards Types as following (V480 has the SCSI Card P/N 375-3057 which is a PCI Dual Ultra3 SCSI Adapter) but (V440 has the SCSI Card P/N 375-3365 which is PCI Dual Ultra3 SCSI Adapter 320)

      2- Add to the above point that both SCSI Cards use a different drivers to work as the V480 SCSI card use the QUS driver but the V440 SCSI Card use the MPT driver

      3- 3310 storage support both SCSI Cards (Both Cards are compatible with the Storage but an issues are published and alerted from sun related to the V440 SCSI 320 card which we need to start by avoiding it)

      ---------------> The problem:

      the problem that an errors come frequently on the both nodes as following:
