Your patch removes the reporting of tgt on iscsi id type and I'm fine with this, but per my understanding it has nothing to do with the problem I had and the fix I suggested. > A simple patch like this doesn't work for you?

To make sure we're on the same page, your patch does four changes to vpd page 0x83 1. doesn't report protocol id anymore (PIV set to zero) 2. reports LUN association (zero) instead of target port association 3. reports T10 identifier type instead of vendor specific 4. uses the T10 IET assigned name in the identifier I am fine with the patch and it allows me to achieve the interop with the vmware stack, to make it clearer I would add the LU association --- tgt.orig/usr/spc.c +++ tgt/usr/spc.c @@ -133,8 +133,8 @@ static void update_vpd_83(struct scsi_lu struct vpd *vpd_pg = lu->attrs.lu_vpd[3]; uint8_t *data = vpd_pg->data; - data[0] = (PIV_ISCSI << 4) | INQ_CODE_ASCII; - data[1] = PIV_VALID | ASS_TGT_PORT | DESG_VENDOR; + data[0] = INQ_CODE_ASCII; + data[1] = ASS_LU | DESG_T10; data[3] = SCSI_ID_LEN; strncpy((char *)data + 4, id, SCSI_ID_LEN); @@ -1029,7 +1029,7 @@ int spc_lu_init(struct scsi_lu *lu) snprintf(lu->attrs.product_rev, sizeof(lu->attrs.product_rev), "%s", "0001"); snprintf(lu->attrs.scsi_id, sizeof(lu->attrs.scsi_id), - "deadbeaf%d:%" PRIu64, tgt->tid, lu->lun); + "IET %04x%04" PRIx64, tgt->tid, lu->lun); snprintf(lu->attrs.scsi_sn, sizeof(lu->attrs.scsi_sn), "beaf%d%" PRIu64, tgt->tid, lu->lun); -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
