Before you begin
Observe the following precautions when replacing a
controller.
CAUTION: HP recommends that you perform
the replacement procedure within seven minutes
from when the controller is removed to when it
is replaced in the enclosure. Ensure all necessary
parts are available so the procedure can be
completed without interruption. Removing a
controller module significantly changes the air
flow within the enclosure. Both controllers must
be installed for the enclosure to cool properly.
If a controller fails, leave it in place in the
enclosure until a new module is available to
install. The enclosure could shut down due to
overheating unless the controller is replaced
within the recommended seven minutes.
Parts can be damaged by electrostatic
discharge. Use proper anti-static protection.
Refer to the documentation that shipped with
your system for additional information.
•Ensure that the backup configuration settings and
correct firmware version of the iSCSI or
iSCSI/FCoE module are available to restore or
install in a replacement controller. Attempt to save
a backup of your iSCSI or iSCSI/FCoE module
configuration file, as noted in this document, if
you have not previously done so.
•Alloy (gray)-colored latches on components like
the controller means the component is
warm-swappable. Halt the I/O of the failing
controller with HP P6000 Command View before
removing this component. See (page 3).
•There are two controllers at the rear of the
controller enclosure. See Figure 1 (page 2) for
the locations.

Saving the iSCSI or iSCSI/FCoE module's
persistent data
NOTE: HP recommends that you save the
iSCSI or iSCSI/FCoE module's persistent data
periodically to avoid data loss from hardware
or software errors.
Be sure to save the configuration information
from each iSCSI or iSCSI/FCoE module before
you replace either controller. Document each of
the iSCSI or iSCSI/FCoE telnet management
port's static or dynamic (DHCP) IP addresses;
they will be needed when configuring the
replacement controller.
To save the iSCSI or iSCSI/FCoE module configuration,
use HP P6000 Command View:
1. In the Navigation pane, select Hardware > iSCSI
Devices > iSCSI Controller 01.
2. Select Set Options.
3. Select Save/Restore configuration.
4. Select either Save Configuration or Full
Configuration Restore.
5. Save the iSCSIContrConfig0001.tgz file.
NOTE: When prompted to save the file,
use a unique file name that includes the
controller number, and it is suggested the
file be saved to a unique array-named
folder.
6. In the Navigation pane, select Hardware > iSCSI
Devices > iSCSI Controller 02.
7. Repeat steps 2 through 5 for the other iSCSI or
iSCSI/FCoE module.
Verifying component failure
Use the following methods to verify component failure:
•Analyze any failure messages received. HP Insight
Remote Support provides a recommended fault
monitoring solution.
•Check status using HP P6000 Command View:
In the navigation pane, select Storage system
> Hardware > Controller Enclosure and then
select a controller.
The status is displayed in the Condition/State
field. An operational state of (Failed)
1.
Page 2
would indicate a fault that may require a
replacement.
2. To check the status of the iSCSI or
iSCSI/FCoE module, in the navigation pane,
select Storage system > Hardware > iSCSI
Devices and then select a controller in the
iSCSI Controller Properties window. The
states are: not installed, good, attention
required, failed, and unknown.
3. To help identify the correct controller, click
Locate > Locate On. This causes the blue UID
indicator to light on the controller module at
the rear of the controller enclosure.
•For information about failures or degraded
performance with the iSCSI or iSCSI/FCoE
module, see the HP P6300/P6500 Enterprise
Virtual Array User Guide. To obtain this guide,
go to http://www.hp.com/support/manuals, click
Disk Storage Systems in the storage section, and
select your model under P6000/EVA Disk Arrays.
•Check the controller status LEDs as shown in
Figure 2 (page 3) and Table 1 (page 3).

Removing a controller
CAUTION: Verify the location of the controller
being serviced. Removing the wrong controller
can result in data loss.
Page 3
NOTE:
•Replacement controllers do not have DIMM
modules, therefore the DIMMs from the
controller being removed must be
transferred to the replacement controller.
•HP recommends that you replace the
controller while the controller enclosure is
powered on to ensure the controller
software on the redundant controller is
copied to the controller being installed.
1. Disconnect all cables from the controller. Ensure
they are marked to facilitate reconnecting later.
2. Remove the controller.
a. Loosen the thumbscrew on the mounting latch
and rotate the latch to the right (1,
Figure 3 (page 4)). The controller will
slightly eject from the enclosure.
b. Position one hand under the controller, and
with the other hand, pull the controller out of
the enclosure (2, Figure 3 (page 4)).

4. Move the small form-factor pluggable (SFP)
modules from the controller being replaced to the
new controller.
5. Push the controller halfway into the controller
enclosure (1, Figure 9 (page 5)).
6. Attach the cables to the two controller device ports
(DP–A and DP–B).
NOTE: Inserting a controller without
connecting the device port cables may
result in soft diagnostic errors being
reported.
7. Fully insert the controller. Move the mounting latch
to the left until fully engaged and the controller is
fully seated in the enclosure (2). The controller
should power up automatically. Tighten the
controller latch thumbscrew.
Figure 9 Installing a controller
8. Attach the FP3 and FP4 Fibre Channel cables or
loopback connectors for unused ports. If installing
loopback connectors, the host port must be
configured in direct connect mode or NL port
mode.
Do not attach the iSCSI or iSCSI/FCoE data
cables yet. Wait and verify that the controller has
successfully booted before continuing to the next
step.
9. Begin restoring the iSCSI or iSCSI/FCoE module
configuration by performing the following steps:
a. Use the iSCSI or iSCSI/FCoE module serial
ports and CLI (as was done when installing
the array) to set the static IP addresses,
network mask, and gateway address of the
management ports used by the replaced
controller. Then install the iSCSI or
iSCSI/FCoE management telnet port cable,
and continue with the HP P6000 Command
View procedure in Step 10.
b. If an IP address was assigned by DHCP and
you plan to continue using the DHCP IP
address, make note of this IP address, install
the iSCSI or iSCSI/FCoE management telnet
port cable, and continue with the HP P6000
Command View procedure in Step 10.
Page 5
10. Complete the iSCSI or iSCSI/FCoE module
configuration by using either HP P6000
Command View or the module CLI. Verify that the
management server has IP connectivity to the
iSCSI or iSCSI/FCoE module management ports
of both controllers.
NOTE: If the configuration file is not
available, you can restore a saved
configuration file from the other iSCSI or
iSCSI/FCoE module. If needed, contact HP
Support for help editing the configuration
file.
Using HP P6000 Command View:
a. In the Navigation pane, select Hardware >
iSCSI Devices, and then select the applicable
iSCSI controller (01 or 02).
b. Select Set Options.
c. Select Register replaced controller. You are
prompted to enter the management port IP
address and perform an update of the
manufacturing data.
NOTE: A refresh may be required at
the Initialized Storage System
Properties top level.
d. Check the firmware version of the iSCSI or
iSCSI/FCoE module using HP P6000
Command View. In the Navigation pane,
select Hardware > iSCSI Devices, and then
iSCSI Controller 01 or 02.
If necessary, upgrade the iSCSI or
iSCSI/FCoE module firmware. See the HP
P6300/P6500 Enterprise Virtual Array
Installation Guide.
e. Select Set Options again, and then select
Save/Restore configuration.
f. Select Full Configuration Restore.
g. Connect the iSCSI or iSCSI/FCoE data
cables to the replacement controller.
Verifying proper operation
After replacing the controller, check the following to
verify the component is operating properly:
NOTE: Wait approximately three minutes for
the system to stabilize, and then check the
controller status.
•Verify the controller health LED is solid green (see
Table 1 (page 3)). If it is not, remove the
controller, and wait at least three minutes before
reseating the controller in the enclosure.
IMPORTANT: Reseating the controller in
less than three minutes can result in timing
issues.
Wait another three minutes for the system to
stabilize. If the health LED does not display solid
green, review the available failure indicators,
check the module error logs and take appropriate
action. See the HP P6300/P6500 Enterprise
Virtual Array User Guide for iSCSI or iSCSI/FCoE
module troubleshooting and error logs.
•From HP P6000 Command View, navigate to the
component as described in the Verifying
component failure section, and check the status.
It should be (Good).
