Connect the Disk and Boot |
System Disk Connect the new disk and boot from a local or remote Solaris 2.x CD. | ||||||
Secondary Disk Connect the new disk and perform a reconfiguration boot, so the system will recognize the disk. | |||||||
Create a Solaris fdisk Partition |
System Disk Only Create the fdisk partition to hold the Solaris operating environment. | ||||||
| |||||||
Create Slices and Label the Disk |
Create disk slices and label the disk if it has not already been done by the disk manufacturer. | ||||||
| |||||||
Create File Systems |
Create UFS file systems on the disk slices with the newfs command. You must create the root (/) or /usr file system (or both) for a system disk. | ||||||
| |||||||
Restore File Systems |
Restore the root (/) or /usr file system (or both) on the system disk. If necessary, restore file systems on the secondary disk. | ||||||
| |||||||
Install Boot Block |
System Disk Only Install the boot block on the root slice, so the system can boot. | ||||||
Follow these guidelines when setting up the fdisk partition.
The disk can be divided into a maximum of four fdisk partitions. One of these partitions must be a Solaris partition.
The Solaris partition must be made the active partition on the disk. The active partition is the one whose operating system will be booted by default at system start-up.
Solaris fdisk partitions must begin on cylinder boundaries.
Solaris fdisk partitions must begin at cylinder 1, not cylinder 0, on the first disk because additional boot information, including the master boot record, is written in sector 0.
The Solaris fdisk partition can be the entire disk or you may want to make it smaller to allow room for a DOS partition. You can also make a new fdisk partition on a disk without disturbing existing partitions (if there is enough room to create a new one).
Solaris slices are sometimes called partitions. This user guide uses the term slice, but some Solaris documentation and programs may refer to a slice as a partition. To avoid confusion, Solaris 2.x documentation tries to distinguish between fdisk partitions (which are supported only on Solaris for x86) and the divisions within the Solaris fdisk partition, which may be called slices or partitions.
This procedure assumes that the system is down.
Disconnect the damaged system disk from the system.
Make sure the disk you are adding has a different target number than the other devices on the system.
You will often find a small switch located at the back of the disk for this purpose.
Connect the replacement system disk to the system and check the physical connections.
Refer to the disk's hardware installation guide for installation details. Also, refer to the x86 Device Configuration Guide about hardware configuration requirements specific to the disk.
Follow steps a-e if you are booting from a local or remote Solaris 2.x CD.
If you are booting from the network, skip step a.
Insert the Solaris 2.x installation CD into the CD-ROM drive.
Insert the Solaris boot diskette into the primary diskette drive (DOS drive A).
Press any key to reboot the system if the system displays the type any key to reboot prompt. Or, use the reset button to restart the system if the system is shut down.
The Multiple Device Boot Subsystem menu is displayed after a few minutes.
Select the CD-ROM drive or net(work) as the boot device from the Multiple Device Boot menu.
The Secondary Boot Subsystem menu is displayed.
Boot the system in single-user mode.
Select the type of installation: b -s |
After a few minutes, the root prompt (#) is displayed.
After you boot the system, you can create slices and a disk label on the disk. Go to "x86: How to Create Disk Slices and Label a Disk".
Become superuser.
If the disk is unsupported by the Solaris software, add the device driver for the disk by following the instructions included with the hardware.
Create the /reconfigure file that will be read when the system is booted.
# touch /reconfigure |
The /reconfigure file will cause the SunOS software to check for the presence of any newly installed peripheral devices when you power on or boot your system later.
Shut down the system.
# shutdown -i0 -g30 -y |
-i0 |
Brings the system down to init state 0 (zero), the power-down state. |
-gn |
Notifies logged-in users that they have n seconds before the system begins to shut down. |
-y |
Specifies the command should run without user intervention. |
The Type any key to reboot prompt is displayed.
Turn off power to the system and all external peripheral devices.
Make sure the disk you are adding has a different target number than the other devices on the system.
You will often find a small switch located at the back of the disk for this purpose.
Connect the disk to the system and check the physical connections.
Refer to the disk's hardware installation guide for installation details. Also, refer to the x86 Device Configuration Guide for hardware configuration requirements specific to the disk.
Turn on the power to all external peripherals.
Turn on the power to the system.
The system will boot and display the login prompt.
After you boot the system, you can create slices and a disk label on the disk. Go to "x86: How to Create Disk Slices and Label a Disk".
Make sure you have read "x86: Guidelines for Creating an fdisk Partition".
Become superuser.

Enter the number of the disk that you want to repartition from the list displayed on your screen.
Specify disk (enter its number): disk-number |
disk-number |
Is the number of the disk that you want to repartition. |
Go into the partition menu (which lets you set up the slices).

See "Using the Free Hog Slice" for more information about the free hog slice.
Create a new partition table by answering yes when prompted to continue.
Do you wish to continue creating a new partition table based on above table[yes]? yes |
Identify the free hog partition (slice) and the sizes of the slices when prompted.
When adding a system disk, you must set up slices for:
root (slice 0) and swap (slice 1) and/or
/usr (slice 6)
After you identify the slices, the new partition table is displayed.
Make the displayed partition table the current partition table by answering yes when asked.
Okay to make this the current partition table[yes]? yes |
If you don't want the current partition table and you want to change it, answer no and go to Step 6.
Name the partition table.
Enter table name (remember quotes): "partition-name" |
partition-name |
Is the name for the new partition table. |
Label the disk with the new partition table when you have finished allocating slices on the new disk.
Ready to label disk, continue? yes |
Quit the partition menu.
partition> quit |
Verify the new disk label with verify command.
format> verify |

After you create disk slices and label the disk, you can create file systems on the disk. Go to "x86: How to Create File Systems".
Become superuser.
Create a file system for each slice with the newfs command.
# newfs /dev/rdsk/cwtxdysz |
/dev/rdsk/cwtxdysZ |
Raw device for the file system to be created. |
See Chapter 28, Mounting and Unmounting File Systems (Tasks), for more information about the newfs command.
Verify the new file system by mounting it on an unused mount point.
# mount /dev/dsk/cwtxdysz /mnt # ls /mnt lost+found |

System Disk |
You need to restore the root (/) and /usr file systems on the disk. Go to Chapter 35, Restoring Files and File Systems (Tasks). After the root (/) and /usr file systems are restored, install the boot block. Go to "x86: How to Install a Boot Block on a System Disk". |
Secondary Disk |
You may need to restore file systems on the new disk. Go to Chapter 35, Restoring Files and File Systems (Tasks).
If you are not restoring file systems on the new disk, you are finished adding a secondary disk. See Chapter 28, Mounting and Unmounting File Systems (Tasks) for information on making the file systems available to users. |
