Hi

I use MegaRAID 9265-8i with 24bay Supermicro chassis and IBM 46M0997 SAS Expander. All works smoothly however one thing drives me crazy. Why all disks have same Slot Number - 0?

sudo megacli -PDList -a0 | grep -e '^Enclosure Device ID:' -e '^Slot Number:'
Enclosure Device ID: 22
Slot Number: 0
Enclosure Device ID: 22
Slot Number: 0
Enclosure Device ID: 22
Slot Number: 0
Enclosure Device ID: 22
Slot Number: 0
Enclosure Device ID: 22
Slot Number: 0
Enclosure Device ID: 22
Slot Number: 0

Thus I cannot use commands that require -physdrv parameter that require unique Enlosure/Slot id.

I am still albe to distinguish Physical Drives by Device Id:
sudo megacli -PDList -aALL | egrep -i "^device id"
Device Id: 25
Device Id: 27
Device Id: 28
Device Id: 32
Device Id: 29
Device Id: 33

But this is not possible to use with -physdrv:
sudo megacli -PDRbld -ShowProg -physdrv[22:33] -aALL

Adapter 0: Device at Enclosure - 22, Slot - 33 is not found.

Exit Code: 0x01


Is it Expander, or Backplane problem? Or controller itself?
