Infrastructure Software

Hi,

I have 15 x 17GB EVA LUNs presented to an OEL4 server with 2 HBA.

When I reboot the server it only sees 11 of these LUNs.

When I restart multipath it then sees the 15 of them.


*+[root@charon ~]# multipath -ll | grep mpath | grep 600508b4 | wc -l+*
+11+

*+[root@charon ~]# service multipathd stop+*
+Stopping multipathd daemon: [ OK ]+

*+[root@charon ~]# service multipathd start+*
+Starting multipathd daemon: [ OK ]+

*+[root@charon ~]# multipath -ll | grep mpath | grep 600508b4 | wc -l+*
+15+
+[root@charon ~]#+

Here is the active lines in the /etc/multipath.conf
*[root@charon ~]# cat /etc/multipath.conf | grep -v ^#*

Any advice appreciated.
