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)

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).

Table 1 Controller status LEDs

IndicationLEDItem

Blue LED identifies a specific controller

within the enclosure and the iSCSI or

iSCSI/FCoE module within the

controller.

Green LED indicates controller health.

LED flashes green during boot and

becomes solid green after boot.

Flashing amber indicates a controller

termination, or the system is

inoperative and attention is required.

Solid amber indicates that the

controller cannot reboot, and that the

controller should be replaced. If both

the solid amber and solid blue LEDs

are lit, the controller has completed a

warm removal procedure, and can be

safely swapped.

Table 1 Controller status LEDs (continued)

IndicationLEDItem

Amber LED indicates the iSCSI or

iSCSI/FCoE module status that is

communicated to the array controller.

MEZZ4

Slow flashing amber LED indicates an

IP address conflict on the management

port.

Solid amber indicates an iSCSI or

iSCSI/FCoE module critical error, or

shutdown.

Green LED indicates write-back cache

status. Slow flashing green LED

indicates standby power. Solid green

LED indicates cache is good with

normal AC power applied.

Amber LED indicates DIMM status. The

LED is off when DIMM status is good.

Slow flashing amber indicates DIMMs

are being powered by battery (during

AC power loss). Solid amber indicates

a DIMM failure.

Halting I/O on the failing controller

To halt I/O to the failing controller, you must halt the

controller (in HP P6000 Command View) and then

shut down the iSCSI or iSCSI/FCoE module (using the

module CLI):

1. In HP P6000 Command View:

a. In the Navigation pane, select Hardware >

Controller Enclosure, and then Controller 01

or 02 (the controller being replaced).

b. On the Initialized Storage System Properties

window, select Shut down, and then select

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)).

Figure 3 Removing a controller

3. Push the blue button on top of the controller

module (1, Figure 4 (page 4)) and slide off the

cover (2). Observe proper anti-static guidelines.

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).
