Can't choose disk in Startup Disk?

Why might a disk not be available to choose in the Startup Disk prefpane?


After a restart, my Xserve (Xserve1,1) started up on the bootable clone (Bay 2) I keep up-to-date with Carbon Copy Cloner. The original system drive (Bay 1) is visible and mounted. I can read from it and write to it and I've verified the disk and repaired permissions. However, I can not choose it in the Startup Disk prefpane.


This is the hardware report for the original system drive:

I thought maybe the volume header was toast for that drive, but bless indicates it's okay...


admin$ bless --info "/Volumes/System"

finderinfo[0]: 287 => Blessed System Folder is /Volumes/System/System/Library/CoreServices

finderinfo[1]: 379380 => Blessed System File is /Volumes/System/System/Library/CoreServices/boot.efi

finderinfo[2]: 0 => Open-folder linked list empty

finderinfo[3]: 0 => No alternate OS blessed file/folder

finderinfo[4]: 0 => Unused field unset

finderinfo[5]: 287 => OS X blessed folder is /Volumes/System/System/Library/CoreServices

64-bit VSDB volume id: 0x371188F36F6E2755


Still digging...
