I do not believe this is true, though I don't have one to test.
Well if you won't accept multiple technically adept people's word on it,
I highly suggest you get one to test instead of speculating.
If this
were true, then we would have had to rewrite the disk drivers to not allow
us to open a device more than once, even if we also closed the device.
I can't imagine anyone allowing such code to be written.
Obviously you have not rewritten the disk drivers to do this, so this is
the wrong line of reasoning.
However, I don't believe this is the context of the issue. I believe that
this release note deals with the use of NVRAID (NVidia's MCP RAID
controller)
which does not have a systems management interface under Solaris. The
solution is to not use NVRAID for Solaris. Rather, use the proven
techniques
that we've been using for decades to manage hot plugging drives.
No, the release note is not about NVRAID.
In short, the release note is confusing, so ignore it. Use x2100 disks as
hot pluggable like you've always used hot plug disks in Solaris.
Again, NO these drives are not hot pluggable and the release note is
accurate. PLEASE get a system to test. Or take our word for it.
