Hot-swap hardware:
You can use certain hardware in DCS3860 to replace a
failed DDM without turning off the storage expansion enclosure. You can
continue to operate your system while aDDM is being removed or installed.
These DDMs are known as hot-swap DDMs.
Before you begin, ensure that you wear an anti-static wrist strap.
Complete the following steps to install hot-swap DDMs in the storage expansion
enclosure:
1.
Read the documentation that is shipped with the DDM.
2.
Check for Service Action Required LEDs described in “Drive drawer LEDs” on
page 65 and “Disk drive LEDs” on page 66. If any amber LEDs are lit, see
“Solving problems” on page 123.
3.
Determine the drive drawer and position into which you want to install the
DDM.
4.
Remove the bezel from the front of the storage expansion enclosure. See
“Replacing the bezel” on page 106 for the steps to remove the bezel.
5.
Open the drive drawer by completing the following steps:
a.
Open the release levers on each side of the drawer and pull them out while
caming the levers away from the chassis. This will release the drawer.
b.
Pull on the extended levers to pull the drive drawer out to its full extension
without removing it from the storage expansion enclosure.
Note:
The fan assemblies spin-up to increase airflow through the enclosure
when a drive drawer is open. This is normal and does not indicate a fault.
Fan speed will return to normal after the drive drawer is closed.
Attention:
To prevent damage to the drive enclosure:
v
For drive enclosures without disk drawers, do not force the drive into the
drive slot at an angle. Ensure that you carefully insert each hard disk drive
straight into the drive slot (horizontal or vertical).
v
For drive enclosures with disk drawers, gently press on the back of the drive
while pulling the lever downward to push the drive into the connector on
the drive drawer board.
