7-2 Netra CT Server Service Manual • February 2007
7.1 Hard Drive
This section describes how to remove and replace an internal hard drive. An internal
hard drive is one that fits in a bay within a server. It is distinguished from an
external hard drive, which is attached by a cable that connects to an I/O board in the
server.
A hard drive is a hot-swappable component only if the hard drive is not being used
by the server. For example, if a hard drive is being used as the primary boot drive,
then that hard drive is not hot-swappable unless disk management software is used
to mirror the boot drive to another device. A hard drive in a Netra CT 410 server is
a hot-swappable drive only if the Netra CT 410 server is running on the Solaris OS
over the network, and not off of the Netra CT 410 server’s hard drive.
In addition, two separate SCSI chains exist in the Netra CT 810 server for the SCSI
devices:
■
The upper hard drive (HDD 0) and the removable media device are both on the
first SCSI chain (c0). Any external SCSI devices attached to the SCSI port on the
rear transition module are on the first SCSI chain.
■
The lower hard drive (HDD 1) is the only SCSI device on the second SCSI chain
(c1) and is used as the boot drive.
The remove-and-replace instructions for hot-swappable drives are covered in this
chapter; the remove-and-replace instructions for cold-swappable drives are covered
in
Chapter 10 in the section Section 10.1, “Cold Swappable Hard dDrives” on
page 10-2 .
■
If you are removing and replacing a faulty hard drive in the server, first go to
Section 7.1.1, “Removing a Hard Drive” on page 7-3 , then go to Section 7.1.2,
“Installing a Hard Drive” on page 7-8 .
■
If you are installing a new hard drive in the server, go to Section 7.1.2, “Installing
a Hard Drive” on page 7-8 .
