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?
[root@pe850 ~]# lsscsi
