You have to be more specific here. What kernel are you using? If you are using a RHEL5 or SLES10 based there is a race-condition where the /sys/block devices are created without all the data entries populated and multipathd can't get all the data from them. And by "not displaying all the paths", you mean that it did not have all of the 4 paths per LUN?? Or that you did not have 1000 multipath device maps? > 2) And when we fail a path by disabling the port, all the path which are failed are not shown in multipath. Do they show when you do "multipathd -k 'show paths'" as orphans? Or do they show up if you run 'multipath' by itself? > > Have we tested multipath with more than 3000 paths? > > Thanks in advance. > > Regards, > Hari > -- > dm-devel mailing list > dm-devel@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/dm-devel -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
