Unable to control LEDs on specific slot

[James Gamei]

Hello

I am trying to use libstoragemgmt (via udisks) to control the ident and
fault LEDs on a 12-disk storage device with an LSI 9400 SAS card.
Everything works except the disk in slot “15” (slots 0, 2, 9 and 11 are
not filled due to layout). For which the SAS address is not found in
_ses_info_get_by_sas_addr. The invoked commands seem to return a list of
addresses for every slot (even the empty ones) *except* slot 15. Does
anyone know why this might happen and/or what can be done to fix it?

Thanks

James

Hi James,

Sorry for the long-long wait.

It might happen when certain port is broken or disabled.

To debug this issue, please provide output of this script after
installed sg3_utils:

```bash
#!/bin/bash

SES_SGS=`lsscsi -g |perl -ne 'print  "$1 " if m|enclosu.+/(sg[0-9]+)|'`

for x in $SES_SGS;do
    sudo sg_ses --join --join /dev/$x --hex -vvvv
done
```

I believe this was addressed with:
