SPARC based systems with GPT-aware firmware and most x86 based systems are installed with an EFI (GPT) label on the root pool disk or disks. See “SPARC: GPT Labeled Disk Support” in Oracle Solaris 11.3 Release Notes for further instructions. In addition, the AI installer has improved the whole_disk keyword syntax so that if whole_disk is set to true , the disk's contents are replaced, even if it has existing partitions or slices. AI installation of a mirrored root pool – Oracle Solaris 10 installation features enable you to create a mirrored root pool during installation. You can use AI manifest keyword syntax to create a mirrored root pool during an Oracle Solaris 11 automated installation. For example, the following syntax creates a mirrored root pool that uses whole disks: <!DOCTYPE auto_install SYSTEM ""> . . . <target> <disk whole_disk="true" in_zpool="rpool" in_vdev="mirrored"> 46 Transitioning From Oracle Solaris 10 to Oracle Solaris 11.3 • December 2018

ZFS Root Pool Device Requirements In general, root pool devices are relabeled and the root pool is created when the system is installed. Review the following additional information about ZFS root pool devices: In Oracle Solaris 11, an SMI (VTOC) label is applied automatically to the root pool disk or disks during an installation on both SPARC and x86 based systems, as shown in the following example: # zpool status rpool pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c7t0d0s0 ONLINE 0 0 0 Chapter 3 • Managing Devices 47
Preparing Disks for ZFS Storage Pools Starting with Oracle Solaris 11.2, an EFI label is applied automatically to the root pool disk or disks during installation on SPARC based systems with GPT-enabled firmware (See “Firmware, Disk Labeling, and EEPROM Changes” on page 122 ) and most x86 based systems. Otherwise, a VTOC disk label is installed on the root pool disk, as shown in the following example: # zpool status rpool pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c7t0d0 ONLINE 0 0 0 When you attach a disk to create a mirrored root pool, use the whole disk syntax as follows: # zpool attach rpool c7t0d0 c7t2d0 Make sure to wait until resilver is done before rebooting. The pool remains in a DEGRADED state until the new disk is resilvered, as shown in the following example: # zpool status rpool pool: rpool state: DEGRADED status: One or more devices is currently being resilvered. The pool will continue to function in a degraded state.
