11     SSwwaappoonn is used to specify additional devices on which paging and swapping
12     are to take place.  The system begins by swapping and paging on only a
13     single device so that only one disk is required at bootstrap time.  Calls
14     to sswwaappoonn normally occur in the system multi-user initialization file
15     /_e_t_c/_r_c making all swap devices available, so that the paging and
16     swapping activity is interleaved across several devices.
17
18     Normally, the first form is used:
19
20     --aa      All devices marked as ``sw'' swap devices in /_e_t_c/_f_s_t_a_b are made
21             available.
22
23     The second form gives individual block devices as given in the system
24     swap configuration table.  The call makes only this space available to
25     the system for swap allocation.

35     There is no way to stop paging and swapping on a device.  It is therefore
36     not possible to make use of devices which may be dismounted during system
37     operation.
