Bigger than 1Tb spindles
By chrisarmes on Jun 16, 2009
Seems a strange title for a blog entry, but I'll explain. As many of you are aware the current Solaris 10 installer is getting somewhat old and painful to use, in fact it is really beyond its useful life.
This is one of the many reasons why in OpenSolaris you have not just IPS but a new installer as well, far more akin to what you see on other operating systems today.
As I discussed in my blog entitled Parallel Patching for Solaris 10, the work we do in this space is highly targeted as it is high risk.
Solaris 10 Update 8 when it ships later this year will have some more enhancements in this space as I've already mentioned. We recently made some more changes in this area, specifically to allow Solaris to work with boot disks of greater than 1TB.
Now this may not sound like such a big deal but in the context of when the installer was designed for Solaris it cannot be underestimated.
So what have we done and why?
The current disk labeling scheme in Solaris (vtoc inside fdisk) breaks down past 1Tb for bootable disks. With Solaris 10 Update 8 not only have the OS level changes been made to allow x86 and SPARC based system to boot from disks up to 2Tb but install changes have also been made to allow the Solaris 10 installer to handle these disks.
