managers,
I am not a solaris expert, so please excuse my infamiliarity in this.
I have an ultra 60 with approved HBAs attached to a fabric that is being
presented LUNs from an IBM shark. I am able to use the LUNs as expected, but
I am having difficulty mapping the device back to the shark's LUNid. I can
do this through a GUI (like ezfibre) but how do I do this natively through
solaris(9)?
the reason I ask is this:
if I present 4 25GB LUNs to a single HBA, and put data onto 3 of the drives
and then decide I want to remove the unused 4th drive, I can find the LUN ID
via ezfibre(serial# drive paramater), but how do I find that number via a
shell? The reason this is important is, dependant upon the HBA, I don't want
to use a specific tool. I understand the nature of fibre channel, and that I
am only presenting the LUN to the HBA, and the shark(or any other appliance)
has no idea what machine the HBA is in, nor how it(the HBA) will present
drives to the host. In AIX I can do it through the drive attributes(lsattr),
but format doesn't give me the info I need (or does it?)
