Alternate Pathing 2.3 Cheatsheet

1. Add AP 2.3 packages: SUWNapr SUNWapu ...
2. Add AP Patches
3. Create at least 3 AP Databases replicas on 3 raw (6mb)
	slices accross controllers and System boards.
	# apdb -c /dev/rdsk/c0t0t0s4 -f
	# apdb -c /dev/rdsk/c1t0d0s4
	# apdb -c /dev/rdsk/c2t0d0s4
4. Creat 3 more on the same slices, except use there alternate
   paths.
	# apdb -c /dev/rdsk/c3t0t0s4 
	# apdb -c /dev/rdsk/c4t0d0s4
	# apdb -c /dev/rdsk/c5t0d0s4

5. Verify entries in /etc/system
6. Refresh copies
	# apdb -Z
7. Verify the state of all copies
	# apconfig -D
8. You may delete any replicas
	# apdb -d /dev/rdsk/c5t0d0s4 -f
9. Create a metha network pathgroup
	# apnet -c -p qfe0 -a qfe4
10. Verify uncommited pathgroup
	# apconfig -N -u
11. Commit the metanetwork (mether0) and verify
	# apdb -C
	# apconfig -N
12. You may switch interfaces
	# apconfig -P mether0 -a qfe0 
13. To delete th emetanetwork
	# apdb -d mether0
 	# apdb -C (apdb -Z will undelete)	 
14. Verify AP sees disks
	# apinst
15. Create disk pathgroup
	# apdisk -c -p sf:2 -a sf:6
	# apconfig -S -u
	# apdb -C
	# apconfig -S	
16. Create /devices ap devices
	# drvconfig -i ap_dmd (Solaris 7 and under)
	# devsadm -i ap_dmd (Solaris 8)
	# apconfig -R (to create /dev/ap links)
17. Put root under ap control
	# apboot mc0t0d0
	# init 6
18. Allow Vxvm to see ap disks.
	# vxdctl enable
19. To switch withing disk pathgroup sf:2
	# apconfig -P sf:2 -a sf:6
20. If ap mark a path with "t" because it once failed,
	fix it, then reset flag
	# apdisk -w sf:6
