Disk enclosures
Disk enclosure components
The D6020 Enclosure Maintenance and Service Guide is the main source of information and will be available
initially from the StoreOnce documentation page at
http://www.hpe.com/info/storeonce/docs.
The standard documentation supplied with field replacement parts for the disk enclosures provides all the
required details, with the following important exception.
The following parts are not hot-pluggable. The system must be taken offline before replacing them.
• I/O module (controller board)
• SAS cable from RAID controller card to the disk enclosures
• Drawer
• Power block
NOTE:
Before replacing any I/O modules or SAS cables, thoroughly check that all cables are fully seated and
connected.
When replacing Drawer Assembly, Power Block Assembly and the I/O Module
Drawer Assembly (828614-001), Power Block Assembly (689128-001) and the I/O Module (828613-001)
components must not be replaced at the same time.
If multiple components require replacing:
Procedure
1. Ensure that the storage filesystem has safely been shutdown. Use the StoreOnce GUI (Device
Configuration—Maintenance—Shutdown) or the StoreOnce CLI (the system shutdown command).
2. Power off the disk enclosure before removing (non hotplug) cables/ components.
3. Replace the first item.
4. Power on the disk enclosure and wait at least 5 minutes to allow the D6020 unique ID information to be
copied onto the replacement part.
5. Power down the disk enclosure and replace the second item.
Power on/off on the disk enclosure
There is a single power on/off button for the disk enclosure on the rear of the unit. You may need to hold down
the power on button (1) on the rear of each unit for up to 30 seconds. Look at the LEDs on the I/O modules
and wait until the Green Status LED (3) remains on, and the Locate LED (2) and the Fault LED (4) are both
off.
