Remove an eUSB Disk
1.
Determine which eUSB disk requires service.
See “Identify Faulted Components” on page 36.
2.
Take the necessary ESD precautions.
See “Prevent ESD Damage” on page 61.
3.
Prepare the CMIOU that contains the faulty eUSB disk for removal and remove it
from the chassis.
See “Servicing CMIOUs” on page 83.
4.
Remove the CMIOU top cover.
Press down on the green button at the top of the cover to disengage the cover from the CMIOU.
While pressing the button, grasp the rear edge of the cover and slide it toward the rear of the
CMIOU until it stops. Lift the cover off.
5.
Remove the eUSB disk.
a.
Use a T10 driver to remove the green screw that secures the eUSB disk to
the CMIOU (panel 1).
b.
Carefully lift the eUSB disk out of the CMIOU (panel 2).
c.
If required, set the eUSB disk aside for installation in the new CMIOU.
When you are replacing a CMIOU that is the only CMIOU in a logical domain guest that
uses iSCSI over IPoIB for booting, and the eUSB disk in that CMIOU is the only disk in
the boot pool, you must install the eUSB disk you remove in the new CMIOU.
