Hello,

I have a two port FC hba in my system.  The hba is properly connecting to a Target, and I can tell it seems all the LUNs exported to it.  However, when I browse through the /sys/class/scsi_host/... directory , and output of "lsscsi", I can see "sd" mappings that are old and invalid (cannot write to them).  In my ouput below, sd[e/f/g/h] and sd[c/d] are invalid.

1. Is there an command I an issue to flush out the older mappings?

2. Is this a bug in the FC driver?
