To Create a Boot Environment and Reconfigure Swap Using a List (Command-Line Interface)

If you have a long list of swap slices, create a swap list. lucreate uses this list for the swap slices in the new boot environment.

The swap slice cannot be in use by any boot environment except the current boot environment or if the -s option is used, the source boot environment. The boot environment creation fails if the swap slice is being used by any other boot environment whether the swap slice contains a swap, ufs, or any other file system.

1. Create a list a swap slices to be used in the new boot environment. The location and name of this file is user-defined. In this example, the contents of the /etc/lu/swapslices file is a list of devices and slices:

   -:/dev/dsk/c0t3d0s2:swap -:/dev/dsk/c0t3d0s2:swap -:/dev/dsk/c0t4d0s2:swap -:/dev/dsk/c0t5d0s2:swap -:/dev/dsk/c1t3d0s2:swap -:/dev/dsk/c1t4d0s2:swap -:/dev/dsk/c1t5d0s2:swap

2. Type:

   # lucreate -m mountpoint:device:fs_type \ -M slice_list -n BE_name

   -m mountpoint:device:fs_type	Specifies the vfstab information for the new boot environment. The file systems that are specified as arguments to -m can be on the same disk or they can be spread across multiple disks. mountpoint can be any valid mount point or – (hyphen), indicating a swap slice. device field can be one of the following: The name of a disk device, of the form /dev/dsk/cnumtnumdnumsnum. The keyword merged, indicating that the file system at the specified mount point is to be merged with its parent fs_type field can be one of the following: vxfs, which indicates a Veritas file system swap, which indicates a swap file system ufs, which indicates a UFS file system
   -M slice_list	List of -m options, which are collected in the file slice_list. Specify these arguments in the format that is specified for -m. Comment lines, which begin with a hash mark (#), are ignored. The -M option is useful when you have a long list of file systems for a boot environment. Note that you can combine -m and -M options. For example, you can store swap slices in slice_list and specify root (/) and /usr slices with -m. The -m and -M options support the listing of multiple slices for a given mount point. In processing these slices, lucreate skips any unavailable slices and selects the first available slice.
   -n BE_name	The name of the boot environment to be created. BE_name must be unique.

   Example 3–5 Create a Boot Environment and Reconfigure Swap Using a List (Command-Line Interface)

   
   

   In this example, swap in the new boot environment is the list of slices that are noted in the /etc/lu/swapslices file.

   # lucreate -m /:/dev/dsk/c02t4d0s0:ufs -m /usr:/dev/dsk/c02t4d0s1:ufs \ -M /etc/lu/swapslices -n second_disk

   When creation of the new boot environment is complete, it can be upgraded and activated (made bootable).
