Replacing a Drive Drawer in a 60-Drive Tray
The steps to replace a failed drive drawer in an E-Series 60-drive tray depend on whether the volumes in the drawer are
protected by Drawer Loss Protection. If all volumes in the drive drawer are in volume groups or disk pools that have Drawer
Loss Protection, you can perform this procedure online. Otherwise, you must stop all host I/O activity and power off the tray
before replacing the drive drawer.
This procedure applies to the following controller-drive trays and expansion drive trays:
• E2660 controller-drive tray
• E2760 controller-drive tray
• E5460 controller-drive tray
• E5560 controller-drive tray
• E5660 controller-drive tray
• DE6600 drive tray
Each of these 60-drive trays has five drive drawers.
And each of the five drawers can hold up to 12 drives.

Before you begin
You need these items for this procedure:
• Antistatic protection
Attention: Possible hardware damage – To prevent electrostatic discharge damage to the drive tray, use proper antistatic
protection when handling drive tray components.
• Replacement drive drawer
• Replacement left and right cable chains
• Orange cable chain removal tool
Note: The cable chain removal tool makes it easier to reach into the enclosure and easier to unplug the cable chain
connectors. If you do not have the tool, you can use your fingers to unplug the connectors.
• Flashlight
• Permanent marker

2. Removing the cable chains on page 4
3. Removing a drive drawer on page 9
4. Installing a drive drawer on page 11
5. Attaching the cable chains on page 13
Preparing to remove a drive drawer
If the drive tray is powered on, you must issue the Set Drawer Service Action Allowed Indicator CLI command to
prevent the controller from accessing the drive drawer. This command also allows you to determine if the drives in the drawer
are in volume groups or disk pools protected by Drawer Loss Protection.
Before you begin
Before issuing the CLI command, confirm that the drive tray meets all of these conditions:
• The drive tray cannot be over temperature.
• Both fans must be installed and have a status of Optimal.
• All drive tray components must be in place.
• The volumes in the drive drawer cannot be in a Degraded state.
Attention: Possible loss of data access – If a volume is already in a Degraded state, and you remove drives from the drive
drawer, the volume can fail.
2Replacing a Drive Drawer in a 60-Drive Tray

About this task
When you issue the Set Drawer Service Action Allowed Indicator CLI command, all drives in the affected drive
drawer are checked to ensure they belong to volume groups or disk pools that have Drawer Loss Protection, as follows:
• If all drives in the drawer are in volume groups or disk pools that have Drawer Loss Protection, the command succeeds, and
the blue Service Action Allowed LED for the drive drawer is illuminated. You do not need to stop host I/O activity or power
down the drive tray to perform this procedure.
• If any drives in the drawer are in volume groups or disk pools that do not have Drawer Loss Protection, a warning is
displayed, indicating that this command should not be completed. To avoid data loss, you must stop all host I/O activity and
power down the drive tray before removing the drive drawer.
Steps
1. Determine if the drive tray is powered on.
• If the power is off, you do not need to issue the CLI command. Go to Removing the cable chains on page 4.
• If the power is on, go to the next step.
2. Type this command on the command line, and press Enter:
SMcli <ctlr_IP1> -c "set tray [trayID] drawer [drawerID]
serviceAllowedIndicator=on;"
In this command:
<ctlr_IP1>
is the identifier of the controller.
[trayID]
is the identifier of the drive tray that contains the drive drawer that you want to replace. Drive tray ID values are 0 to
99. You must enclose the value for trayID in square brackets.
[drawerID]
is the identifier of the drive drawer that you want to replace. Drawer ID values are 1 (top drawer) to 5 (bottom
drawer). You must enclose the value for drawerID in square brackets.
Example
This command turns on the blue Service Action Allowed LED for the top-most drawer in drive tray 10:
SMcli <ctlr_IP1> -c "set tray [10] drawer [1]
serviceAllowedIndicator=on;"
3. Determine if you need to stop host I/O activity, as follows:
• If the command succeeds, and the blue Service Action Allowed LED is illuminated, you do not need to stop host I/O
activity. All drives in the drawer are in volume groups or disk pools that have Drawer Loss Protection. Go to Removing
the cable chains on page 4.
Attention: Possible damage to drives – Wait 30 seconds after the blue Service Action Allowed LED comes on before
you open the drive drawer. Waiting 30 seconds allows the drives to spin down, which prevents possible damage to the
hardware.
• If a warning is displayed indicating that this command should not be completed, you must stop host I/O activity before
removing the drawer. The warning is displayed because one or more drives in the affected drawer are in volume groups
or disk pools that do not have Drawer Loss Protection. To avoid losing data, you must complete the next steps to stop
host I/O activity and to power off the tray.
Preparing to remove a drive drawer 3

4. Ensure that no I/O operations are occurring between the storage array and all connected hosts. For example, you can perform
these steps:
• Stop all processes that involve the LUNs mapped from the storage to the hosts.
• Ensure that no applications are writing data to any LUNs mapped from the storage to the hosts.
• Unmount all file systems associated with volumes on the array.
Note: The exact steps to stop host I/O operations depend on the host operating system and the configuration, which are
beyond the scope of these instructions. If you are not sure how to stop host I/O operations in your environment, consider
shutting down the host.
Attention: Possible data loss – If you continue this procedure while I/O operations are occurring, you might lose data.
5. If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary storage array.
6. Wait for five minutes to allow any data in cache memory to be flushed to disk.
7. From the title bar of the Array Management Window, select Monitor > Reports > Operations in Progress.
8. Wait for all operations shown on the Operations in Progress window to complete before continuing with the next step.
9. Power off the tray as follows:
If you are... Follow these steps...
Replacing a drive drawer in a
controller-drive tray a. Turn off both power switches on the controller-drive tray.
b. Wait for all LEDs on the controller-drive tray to go dark.
