Hiho,

I have a Enterprise 250 here with a 18G disk in it. Actually there is
installed OpenSolaris on /dev/dsk/c0t0d0s0 (16G). Now I want to add a
swap in /dev/dsk/c0t0d0s1 (2G). When I do a:

# df -h
....
swap 245M 1,1M 244M 1% /etc/svc/volatile
swap 244M 64K 244M 1% /tmp
swap 244M 48K 244M 1% /var/run
....

After a:
# swap -a /dev/dsk/c0t0d0s1
# df -h
....
swap 2,2G 1,1M 2,2G 1% /etc/svc/volatile
swap 2,2G 64K 2,2G 1% /tmp
swap 2,2G 48K 2,2G 1% /var/run
....

Which looks good to me. The problem is that I need to do it every time I
boot the machine. (How) Can I add the new swap to /etc/vfstab?

Thanks, Marek

which is explained in "man vfstab"

device device mount FS fsck mount mount
to mount to fsck point type pass at boot options

/etc/vfstab can be used to specify swap areas. An entry so
specified, (which can be a file or a device), will automati-
cally be added as a swap area by the /sbin/swapadd script
when the system boots. To specify a swap area, the device-
to-mount field contains the name of the swap file or device,
the FS-type is "swap", mount-at-boot is "no" and all other
fields have no entry.
