Hello,

I have a problem when I try to run format command to label a disk of 1TB under solaris 8.

/pci@8,700000/lpfc@4/sd@e,3

Specify disk (enter its number)[115]: 114

selecting c9t14d3

[disk formatted]

Disk not labeled. Label it now? y

Solaris 8 supports LUNS that are less than 1TB in size.You have to have later versions of 9 before you can use EFI labels and multi-terabyte luns.-- Darren

I think maybe if you split it into two luns, you can stitch them back together with svm.But even thats not certain.

But even thats not certain.

Depends on what you're going to do with the device at that point. UFS on Solaris also does not support volumes 1TB or larger. So you'd have to use it as a raw slice space or a filesystem that did support larger sizes.

You need later versions of Solaris 9 to get mutli-terabyte UFS support. (a separate issue from multi-terabyte LUN support).
