Solaris Express Installation Guide: Custom JumpStart and Advanced Installations

client_swap Profile Keyword

client_swap swap_size

client_swap defines the amount of swap space, swap_size in Mbytes, to allocate for each diskless client. If you do not specify client_swap in the profile, 32 Mbytes of swap space is allocated by default.

Note –

You can use client_swap only when system_type is specified as server.

Example 8–9 client_swap Profile Keyword

The following example specifies that each diskless client is to have a swap space of 64 Mbytes.

client_swap 64

How the Size of swap Is Determined

If a profile does not specify the size of swap, the JumpStart program determines the size of the swap space, based on the system's physical memory. Table 8–5 shows how the size of swap is determined during a custom JumpStart installation.

Table 8–5 Determining swap Size

Physical Memory (in Mbytes) 

Swap Space (in Mbytes) 







Greater than 512 


The JumpStart program makes the size of swap no more than 20 percent of the disk where swap is located. The allocation is different if the disk contains free space after laying out the other file systems. If free space exists, the JumpStart program allocates the free space to swap, and if possible, allocates the amount that is shown in Table 8–5.

Note –

Physical memory plus swap space must total a minimum of 32 Mbytes.
