d. Vary off the volume group as follows:
# varyoffvg vgu01
e. Change the reserve_lock setting as follows:
# chdev -l hdiskpower10 -a reserve_lock=no
hdiskpower10 changed
f. Confirm that the change was made as follows:
# lsattr -El hdiskpower10 |grep reserve
noreserve_lock no Reserve device on open
True
g. Vary on the volume group as follows:
# varyonvg vgu01
h. Mount the file system as follows:
# mount /u01
i. Start the Oracle database application.

Validations during router insertion process
Removing first direct path
from controller port (for
example, Port A) 1. Issue the powermt display dev=all command to display the path state and
physical disk associated with this PowerPath device. The removed path shows up
as dead. The other active and alive path continues the I/O
2. Issue the cfgmgr command to view updated path information. PowerPath
automatically updates the path status upon detecting a path failure.
.
Adding router path for the
removed controller port (for
example, Port A) 1. Zone in the router presented target controller for Port A.
2. On the AIX host, issue the cfgmgr command.
3. Issue the powermt display dev=all command to list the additional path to
the same LUN along with direct path.
Issue the powermt display dev=all command to display the path state and

Adding router path for the
removed controller port (for

2. On the AIX host, issue the cfgmgr command to view updated path information.
3. Issue the powermt display dev=all command to view the additional path to
the same LUN, along with the first router path.
These validations use the method described in “Zoning in presented targets: Method 1” .
Alternatively, you can use the method described in “Zoning in presented targets: Method 2” .

Ensure that the /dev/dsk/c*t*d* entries of the alternate paths (PVLinks) have been
added to the volume group for all the LUNs forming the volume group by issuing the
following command:
vgdisplay -v testvg
