SUMMARY: Mirroring swap?

Gents,

Thanks everyone for the responses!!!
Here's what I've done...

mkfile 1024m /home/swapfile
swap -a /home/swapfile
swap -d /dev/dsk/c1t0d0s1

metainit -f d11 1 1 c1t0d0s1
metainit d1 -m d11

swap -a /dev/md/dsk/d1
swap -d /opt/swapfile

metainit -f d21 1 1 c1t1d0s1
metattach d1 d21

vi /etc/vfstab

And now the system uses the new, mirrored swap
file system without any reboot!
Is there any good way to test that it's really
satisfied with the new, mirrored swap?
If I issue the swap -l it shows that
the box uses the new file system.

# swap -l
swapfile             dev  swaplo blocks   free
/dev/md/dsk/d1      85,1      16 840272 840272

But I'm just not sure that it really won't have
any problem with the new settings in the future.

Thanks in advance!

Regards,

John
