mirroring root disk using svm - but no free slices for metadb's
Hi all,

we have an existing system that was configured using just one of the (two) internal disks. I want to mirror the disk using SVM, but have realised there is no free slice for creating the metadb's. Is there a workaround I can use for this?

In the past we have always kept slice 7 free - but this is not available:

Code:
AVAILABLE DISK SELECTIONS:
       0. c1t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
          /pci@1f,700000/scsi@2/sd@0,0
       1. c1t1d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
          /pci@1f,700000/scsi@2/sd@1,0
Specify disk (enter its number): ^D
