10-2 Netra CT Server Service Manual • February 2007
10.1 Cold Swappable Hard dDrives
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.
Though the Netra CT 410 server has one disk bay and the Netra CT 810 server has
two, the procedures for removal and replacement of a disk are the same for both
types of servers.
A hard drive is a cold-swappable component if it is being used by the server. For
example, if a hard drive is being used as the primary boot drive, then that hard drive
is a cold-swappable component unless disk management software is used to mirror
the boot drive to a second hard drive installed in the server. For that reason, a hard
drive in a Netra CT 410 server is a cold-swappable disk drive, unless it is running on
the Solaris OS over the network and not off of the hard drive, in which case it
becomes a hot-swappable component.
Instructions for removing and replacing a cold-swappable hard drive are covered
here; instructions for removing and replacing a hot-swappable hard drive are
covered in
Section 7.1, “Hard Drive” on page 7-2 .
10.1.1 Removing a Cold-Swappable Hard Drive
Note –
The instructions in this section do not cover unconfiguration procedures that
might be necessary if you are removing a hard drive that is under the control of any
disk management software, such as Solaris Volume Manager or Solstice DiskSuite. If
you are running disk management software on your system, refer to the
documentation that came with the disk management software for instructions on
releasing a hard drive from the control of the software before proceeding with these
instructions.
1. Complete the power off steps.
See Section 2.3, “Powering Off the Server” on page 2-7 for those instructions.
2. Attach the antistatic wrist strap.
See Section 1.2, “Attaching the Antistatic Wrist Strap” on page 1-2 .
