Hi,everyone.
I'm now working on something about creating a virtual disk(lun). The following
questions confused me for quite a few days.
1. How is a physical disk scaned and probed in Solaris? Which drivers are
involved in this process?
2. Does the bus_ops structure play a role in the hardware probing process? If
so, which entry point in the bus_ops probe the disk?
3. Is the mpxio open frame under which I can make my own multipath software? If
so, how can I use the confusing vhci, phci and client?
4. I want to make a virtual disk finally. I know that the device node for this
virtual disk must be a pseudo device. It's also most likely that this pseudo
device should be a nexus node. If the node has its devo_bus_ops set to
scsi_hba_busops, does it mean that the system will probe the child
antomatically? And, if the OS succeeds in probing(given the actual physical lun
path), does the OS "see" a virtual disk automatically? Am I right? What else
should I do?
Thanks a lot.
