Chapter 9 Replacement and Installation of a Hard Disk Drive (HDD) 9-3
9.1 Accessing a Hard Disk Drive
Caution – To ensure that you and bystanders are not exposed to harm and to
prevent damage to the system, observe the ESD safety precautions. Section 1.1, “ESD
Precautions” on page 1-1.
9.1.1 Active Replacement
For active replacement, operation varies by the hard disk drive configuration.
■ In hardware RAID
Verify the faulty hard disk drive in advance of the operation. For details, see the
SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers Administration Guide.
■ In software RAID
See the manuals for the software in use.
■ When hardware RAID and software RAID are not used
Release the hard disk drive from the domain. This procedure includes the steps of
using the cfgadm command to check the Ap_Id, and for releasing the hard disk
drive. For details, see Section 4.3.1, “Releasing a FRU from a Domain” on
page 4-5.
Note – In a nonmirrored configuration, data in the hard disk drive will be lost. Back
up the data in advance of the operation. Active replacement for a boot device in a
nonmirrored configuration is not available.
9.1.2 Hot Replacement
For hot replacement, stop the domain.
The hot replacement of the hard disk drive is almost the same as the cold
replacement. See Section 4.5.1, “Powering off the Server” on page 4-12 and perform
the operation with the power cord being connected to power outlets.
