Some SAS JBODs support zoning. This feature allows individual SAS targets to be accessible by only some initiator ports. One application would be connecting two servers to the same JBOD, but they wouldn't be able to see each other's disks. A zoned JBOD should also prohibit initiators from accessing SES elements corresponding to inaccessible SAS targets. It reports that by setting the element's status code to 0x8 (No Access Allowed). The bug is that when doing "sesutil (fault|locate) all ...", sesutil will attempt a ENCIOC_SETELMSTAT ioctl for every single element, even the inaccessible ones. The enclosure will reject the command, the kernel will return EINVAL, and sesutil will exit. The solution is to check the element's status, and skip trying to set it if the status is 0x8. But if the user actually supplied a ses ID, then assume that he knows what he's doing and try to set it anyway.
