Monitoring the multipath devices

After HP P6000 Command View has presented the virtual disks to the Solaris host, enter the
following commands to monitor the configuration:
1.
iscsiadm list target -S
This command lists targets with their presented LUNs. In a multipath environment, the same
LUN should appear under different P6000 EVA port targets from the same controller.
Example:
iscsiadm list target -S
Target: iqn.1986-03.com.hp:fcgw.mpx200.0834e00028.b2.01.50014380025c4179
Target: iqn.1986-03.com.hp:fcgw.mpx200.0834e00028.b1.01.50014380025c417d
2.
mpathadm list lu
This command displays the total and operational path count for each logical unit. It displays
both the controller and device path counts.
Example:
#mpathadm list lu
