Chapter 4 FRU Removal Preparation 4-3
4.2 Active Replacement
In active replacement the Solaris OS must be configured to allow the component to
be replaced. Active replacement has four stages:
■ Section 4.2.1, “Disconnecting a FRU from a Domain” on page 4-3
■ Section 4.2.2, “Disconnecting and Replacing a FRU” on page 4-5
■ Section 4.2.3, “Configuring a FRU into a Domain” on page 4-6
■ Section 4.2.4, “Confirming the Hardware” on page 4-7
Note – If the hard disk drive is the boot device, it is necessary to replace it according
to the cold replacement procedure. However, if the disk mirroring software or other
support software can disconnect the relevant boot disk from Solaris OS, active
replacement can be performed.
