Subject: [PATCH 6/6] nvme-cli: Make connect-all matching be case insensitive
|
|
|
|
The comparison routine that checks discovery controller traddr with a
|
|
discovery log traddr uses a simple strncmp. For FC, which kicks off
|
|
connect-all requests vay systemd, the nvme-fc transport will build
|
|
traddr strings with lower case hexadecimal. Some FC discovery
|
|
controllers return traddr strings with upper case hexadecimal. There
|
|
was is no rqmt in the NVME-FC spec that it be upper or lower case.
|
|
Given the case difference, the connect-all fails the match logic and
|
|
doesn't connect to storage.
|
|
|
|
Revise the traddr comparison routine to duplicate the strings and
|
|
convert them to lower case for comparison.
