Just some thoughts about patching zones (and the global) when using
Sun Cluster 3.1 or 3.2 for minimizing the total downtime.
If using the zone-path on mirrored SAN-disks separated from the LUN's
or devices monted in the zone where the applications reside.
Would it be possible to detach the mirror of the zone-root-filesystem
and mount it on the node that is the target for patching?
I surely see issues like the need of temporarily reconfiure the zone
configuration on the patching node, zone-path, IP-address, detach and
attach storage from metasets, etc.
Would it be possible in some way?
