Verifying Your Configuration
Verify Your Configuration with PowerPath
1. Save the server’s PowerPath configuration with the following
PowerPath command:
powermt save
This command creates the
powermt.ctm
configuration file.
2. If you connected a new server to an existing storage system, stop
all applications accessing the storage system and disable user
logins to the server.
3. View the virtual disks available to the server:
powermt display dev=all
4. Choose one available virtual disk to receive data (I/O) for the
test.
5. View the paths to the chosen virtual disk:
powermt display dev=
x
every=2
where
x
is a pseudo device that represents the chosen virtual disk.
6. Start sending data to a virtual disk by writing data to it.
7.
Identify the HBA sending data to the virtual disk by viewing the
output of the
powermt display dev=
x
every=2
command, and
disconnect the cable to that HBA
.
8. View the output of the
powermt display dev=
x
every=2
command, and verify that:
• The state of the uncabled paths becomes “dead.”
• Data continues to be sent on the remaining path(s) to the
virtual disk
,
indicating that the failover path was successful
and that PowerPath is working properly.
If PowerPath is not working properly, refer to the "Troubleshoot"
section on the AX100 support website or the
AX100-Series
Documentation
CD.
9. Reconnect the cable that you disconnected from the HBA.
