3.2.4 Installing Drives in Bank E
Installation of drives in bank E is exactly the same as the procedure for installing
drives in bank D.
3.2.5 Disk Carriers
The disk carriers have two lights which enable you to determine the status of the
drive. Figure 15 shows a diagram of the lights and the spin down button, and
Table 11 explains their meanings.
Figure 15. Disk Drive Light
During normal operation of AIX, both of the lights on the disk carrier will be on. If a
drive is removed from the ODM, for example, by using:
rmdev -d -l hdiskx
the drive will spin down, and the amber light will go out.
