IsMegaRaidSysPath and NameByDiskID do not work for SAS3508 (UCSC-SAS-M5HD) #101
Description
NameByDiskID and IsMegaRaidSysPath do not seem to work for the SAS3508 controller. This was the same controller named in #98 which is really just a HBA (host bus adapter), as it apparently does not support raid (per lack of RAID entries in 'Capabilities' of storcli /c0 show all).
The information I have from the one system I had access to looked like this:
/sys/bus/scsi/devices/target7:0:1/7:0:1:0/block/sdd
/sys/bus/scsi/devices/target7:0:0/7:0:0:0/block/sdc
Those correspond to EID/Slot/DiskID of 2/2/1 and 2/1/0 respectively. They had udev syspath of:
/devices/pci0000:17/0000:17:00.0/0000:18:00.0/host7/port-7:0/expander-7:0/port-7:0:1/end_device-7:0:1/target7:0:1/7:0:1:0/block/sdd
/devices/pci0000:17/0000:17:00.0/0000:18:00.0/host7/port-7:0/expander-7:0/port-7:0:0/end_device-7:0:0/target7:0:0/7:0:0:0/block/sdc
