The following task map identifies the procedures for setting up a disk for a UFS root file system or a disk for a UFS file system on a SPARC based system.
|
A disk can contain the UFS root (/) and /usr file systems, user or data file systems, or a combination of file systems. If the disk contains the UFS root (/) or /usr file systems, you have two ways to recover:
You can reinstall the entire Oracle Solaris OS.
Or, you can replace the disk and restore your Oracle Solaris OS file systems from a backup medium.
A disk that contains user or data file systems can be replaced and the file systems restored, if necessary, without having to reinstall or reboot the system.
You can use this procedure to replace a disk that contained the UFS root or /usr file system. Refer to your hardware installation guide for information on replacing a disk.
|
After a few minutes, the root prompt (#) is displayed.
Create slices for the UFS root and /usr file systems and a disk label on the disk. Go to SPARC: How to Create Disk Slices for a UFS File System.
If you are adding a disk with an EFI disk label, see EFI Disk Label for more information.
Generally, most modern bus types support hot-plugging. This means you can insert a disk in an empty slot and the system recognizes it. For more information about hot-plugging devices, see Chapter 6, Dynamically Configuring Devices (Tasks).
Refer to the disk's hardware installation guide for details.
After the disk is connected, create slices and a disk label on the disk. Go to SPARC: How to Create Disk Slices for a UFS File System.
# format
A numbered list of available disks is displayed.
Specify disk (enter its number): disk-number
disk-number is the number of the disk that you want to repartition.
format> partition
partition> print
partition> modify
Choose base (enter number) [0]?1
For more information about the free hog slice, see Using the Free Hog Slice.
Do you wish to continue creating a new partition table based on above table[yes]? y
When adding a system disk, you must set up slices for:
root (slice 0) and swap (slice 1)
/usr (slice 6)
After you identify the slices, the new partition table is displayed.
For an example of creating disk slices, see Example 12-1.
Okay to make this the current partition table[yes]? y
If you do not want the current partition table and you want to change it, answer no and go to Step 6.
Enter table name (remember quotes): "partition-name"
where partition-name is the name for the new partition table.
Ready to label disk, continue? yes
partition> q
format> verify
format> q
Example 12-1 SPARC: Creating Disk Slices for a UFS Root File System
The following example shows the format utility being used to divide a 18-GB disk into three slices: one slice for the root (/) file system, one slice for the swap area, and one slice for the /usr file system.

After you create disk slices and label the disk, you can create file systems on the disk. Go to SPARC: How to Create a UFS File System.
# newfs /dev/rdsk/cwtxdysz
where /dev/rdsk/cwtxdysx is the raw device for the file system to be created.
For more information about the newfs command, see Chapter 17, Creating and Mounting File Systems (Tasks) or newfs(1M).
# mount /dev/dsk/cwtxdysz /mnt # ls lost+found
Disk for a UFS root file system – You need to restore the root (/) and /usr file systems on the disk.
Go to Chapter 25, Restoring UFS Files and File Systems (Tasks).
After the root (/) and /usr file systems are restored, install the boot block. Go to SPARC: How to Install Boot Blocks for a UFS Root File System.
Disk for a UFS file system – You might need to restore file systems on the new disk. Go to Chapter 25, Restoring UFS Files and File Systems (Tasks). If you are not restoring file systems on the new disk, you are finished adding a secondary disk.
For information on making the UFS file systems available to users, see Mounting and Unmounting Oracle Solaris File Systems.
# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/cwtxdys0
For more information, see installboot(1M).
# init 6
Example 12-3 SPARC: Installing a Boot Block for a UFS Root File System
The following example shows how to install the boot block on a UFS root file system.
# installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0
