4-4 SPARC Enterprise M4000/M5000 Servers Service Manual • December 2010
4.2 Active Replacement
In active replacement the Oracle Solaris OS must be configured to allow the
component to be replaced. Active replacement has four stages:
■ Section 4.2.1, “Removing a FRU From a Domain” on page 4-4
■ Section 4.2.2, “Removing and Replacing a FRU” on page 4-5
■ Section 4.2.3, “Adding a FRU Into a Domain” on page 4-5
■ Section 4.2.4, “Verifying Hardware Operation” on page 4-6
Note – If the hard disk drive is the boot device, the hard disk will have to be
replaced using cold replacement procedures. However, active replacement can be
used if the boot disk can be isolated from the Oracle Solaris OS by disk mirroring
software and other software.
