Which is true regarding the disk drive?
A.
This disk configuration could be used as a ZFS root disk.
B.
This disk contains an SMI disk label.
C.
Slice 7 represents the entire disk and cannot be used as a slice for a file system
D.
The disk contains an EFI disk label.
Explanation:
Installing a ZFS Root Pool
The installer searches for a disk based on a recommended size of approximately 13 GB.
Reference: Oracle Solaris ZFS Administration Guide, Managing Your ZFS Root Pool
D
We recommend that you create non-root pools with whole disks but keep in mind that root pool disks need an SMI label from which to boot.
D is correct
The disk that is intended for the root pool must have an SMI (VTOC) label.
hence if A is correct and B is correct.
D is correct.
A ZFS root disk with an EFI label looks like this:
partition> p
Current partition table (original):
Total disk sectors available: 67092413 + 16384 (reserved sectors)
Part Tag Flag First Sector Size Last Sector
0 BIOS_boot wm 256 256.00MB 524543
1 usr wm 524544 31.74GB 67092446
2 unassigned wm 0 0 0
3 unassigned wm 0 0 0
4 unassigned wm 0 0 0
5 unassigned wm 0 0 0
6 unassigned wm 0 0 0
8 reserved wm 67092447 8.00MB 67108830
A non root disk, also EFI labeled, looks like this:
partition> p
Current partition table (original):
Total disk sectors available: 33537981 + 16384 (reserved sectors)
Part Tag Flag First Sector Size Last Sector
0 usr wm 256 15.99GB 33538014

2 unassigned wm 0 0 0
3 unassigned wm 0 0 0
4 unassigned wm 0 0 0
5 unassigned wm 0 0 0
6 unassigned wm 0 0 0
8 reserved wm 33538015 8.00MB 33554398
D
Exhibit shows that this disk has an EFI label because it identifies first and last sectors
it’s a EFI labelled disk without boot partition , so it can’t be used as ZFS boot disk .
But it’s EFI labbeld disk so answer is D
check with (format -e)
