Replacing a drive drawer in E5760 and E2860 shelves
The steps to replace a failed drive drawer in an E-Series E5760 controller shelf, E2860 controller shelf or a DE460C drive shelf
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 shelf before replacing the drive drawer.
This procedure applies to the following controller shelf and drive shelf:
• E5760 controller shelf
• E2860 controller shelf
• DE460C drive shelf
Each of these 60-drive shelves has five drive drawers.
And each of the five drawers can hold up to 12 drives.

Preparing to remove a drive drawer
If the drive shelf 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. If the command fails, you will need to power off the
controller shelf before replacing the drawer.
Before you begin
Before issuing the CLI command, confirm that the drive shelf meets all of these conditions:
• The drive shelf cannot be over temperature.
• Both fans must be installed and have a status of Optimal.
• All drive shelf components must be in place.
2

• 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.
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. You
do not need to stop host I/O activity or power down the shelf 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 could not be completed. To avoid data loss, you must stop all host I/O activity and
power down both the drive shelf and the controller shelf before removing the drive drawer.
Steps
1. Determine if the drive shelf 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 5.
• If the power is on, go to the next step.
2. Type this command on the command line, and press Enter:
SMcli <ctlr_IP1> -p "array_password" -c "set tray [trayID] drawer [drawerID]
serviceAllowedIndicator=on;"
Command Description
<ctlr_IP1> The identifier of the controller.
array_password The password for the storage array. You must enclose the value for
array_password in double quotation marks ("").
[trayID] The identifier of the drive shelf that contains the drive drawer that you want to
replace. Drive shelf ID values are 0 to 99. You must enclose the value for trayID in
square brackets.
[drawerID] 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 ensures you can remove the top-most drawer in drive shelf 10:
SMcli <ctlr_IP1> -p "safety-1" -c "set tray [10] drawer [1]
serviceAllowedIndicator=forceOnWarning;"
3. Determine if you need to stop host I/O activity, as follows:
• If the command succeeds, 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 5.
Attention: Possible damage to drives – Wait 30 seconds after the command completes before you open the drive
drawer. Waiting 30 seconds allows the drives to spin down, which prevents possible damage to the hardware.
Preparing to remove a drive drawer 3

• If a warning is displayed indicating that this command could 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 drive shelf and the controller shelf.
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, the host application
might lose data because the storage array will not be accessible.
5. If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary storage array.
6. Wait for any data in cache memory to be written to the drives.
The green Cache Active LED on the back of each controller is on when cached data needs to be written to the drives. You
must wait for this LED to turn off.
