live upgrade SUN cluster

Hi, Guys

On this weekend I have to upgrade Solaris 10 2 node SUN cluster from u4 to u9. I have not touch Sun cluster for a while so I need some help. Can anybody let me know what I have to do specifically for this upgrade?

Thank you very much

Thank you DukeNuke2 for your reply. I looked in this doc, but it's a little bit confusing. After I disable groups do I have to boot to none cluster state or proceed with upgrade and reboot after?

since you said you want to use "live upgrade" you will upgrade and patch the ABE (alternate boot environment) and so you don't need to reboot...

good enough, thank you very much

The following example shows the names of DID device d3s3, which corresponds to /global/.devices/node@2, changed to its physical device names and the global entry removed:

Original:/dev/did/dsk/d3s3 /dev/did/rdsk/d3s3 /global/.devices/node@2 ufs 2 no globalChanged:dev/dsk/c0t0d0s3 /dev/rdsk/c0t0d0s3 /global/.devices/node@2 ufs 2 no -

this is from doc. When I changed to slices, what disk do I have to use primary or alternative?

Thank you

in the beginning of doc it says to take SG offline and disable it, but in the liveupgrade it says to move to another node, so I can't decide what is the best solution. Also, what is the diff if I comment global entries in vfstab file or change them for local devices?
