Is there any Secure Path commands that can be run to show paths on a server?

[John E. Goetz]

We have a HP EVA3000 storage unit attached via 2 HBA fibers on L3000 server. I see both HBA's and EVA3000 connections in ioscan but when doing a lssf * in /dev/rdsk, only one controller is configured. Also seeing only 1 path in SAM. How does Secure Path work?

hi,

to show the SP info.
# spmgr display

GOOD LUCK!!

spmgr display -a[v] [adapter]
-c[v] [controller_ser_num]
-d[v] [device]
-p path-Instance
-r[v] [WWNN]

Secure Path eliminates the RAID controller, Host Bus Adapter (HBA), and
interconnect hardware (cables, switches, and connectivity devices) as single
points of failure in the storage system.
By using redundant hardware and advanced RAID technology, Secure Path
enhances fault tolerance and storage system availability by providing automated
failover capability.
Redundant physical connections define separate paths in a Secure Path hardware
configuration. Each path originates at a unique HBA port on a server and ends at a
unique RAID controller port in the storage system.

The Secure Path software detects the failure of I/O operations on a failed path and
automatically re-routes traffic to other available paths. Secure Path software
gathers alternate paths through available SAN switches, controllers, controller
ports, and HBAs. Path failover is completed seamlessly, without process
disruption or data loss.


The Secure Path management utility (sbin/spmgr) displays device
information, actively manages paths to each device, and sets driver options,
such as load balancing, path verification, and auto-restore

# spmgr display

This commands shows the status of the operational controllers and whether load balance is set on, as well as which path has been set as prefered path.

type
#spmgr

this shows all possible commands and description
