一、封装系统盘
1、准备
若要减小封装失败的可能性，请确保磁盘：
包含少量不属于任何分区的空闲空间（在磁盘的起始或末尾处）
包含两个空闲分区
包含表示整个磁盘的 s2 片

Encapsulate one or more disks
Menu: VolumeManager/Disk/Encapsulate
Use this operation to convert one or more disks to use the Volume Manager.
This adds the disks to a disk group and replaces existing partitions
with volumes. Disk encapsulation requires a reboot for the changes
to take effect.
More than one disk or pattern may be entered at the prompt. Here are
some disk selection examples:
all: all disks
c3 c4t2: all disks on both controller 3 and controller 4, target 2
c3t4d2: a single disk (in the c#t#d# naming scheme)
xyz_0 : a single disk (in the enclosure based naming scheme)
xyz_ : all disks on the enclosure whose name is xyz

Continue operation? [y,n,q,?] (default: y)
You can choose to add this disk to an existing disk group or to
a new disk group. To create a new disk group, select a disk group
name that does not yet exist.
Which disk group [<group>,list,q,?] (default: rootdg) rootdg
There is no active disk group named rootdg.
Create a new group named rootdg? [y,n,q,?] (default: y) y
Use a default disk name for the disk? [y,n,q,?] (default: y) n
A new disk group will be created named rootdg and the selected
disks will be encapsulated and added to this disk group with
disk names that will be specified interactively.
c1t1d0
Continue with operation? [y,n,q,?] (default: y)
The following disk has been selected for encapsulation.
Output format: [Device_Name]
c1t1d0
Continue with encapsulation? [y,n,q,?] (default: y)
Enter disk name for c1t1d0 [<name>,q,?] (default: bootdg01) bootdisk
A new disk group rootdg will be created and the disk device c1t1d0 will
be encapsulated and added to the disk group with the disk name bootdg01.
Enter desired private region length
[<privlen>,q,?] (default: 2048)
The c1t1d0 disk has been configured for encapsulation.
The first stage of encapsulation has completed successfully. You
should now reboot your system at the earliest possible opportunity.
The encapsulation will require two or three reboots which will happen
automatically after the next reboot. To reboot execute the command:
shutdown -g0 -y -i6
This will update the /etc/vfstab file so that volume devices are
used to mount the file systems on this disk device. You will need
to update any other references such as backup scripts, databases,
or manually created swap devices.
Encapsulate other disks? [y,n,q,?] (default: n)

Add or initialize disks
Menu: VolumeManager/Disk/AddDisks
Use this operation to add one or more disks to a disk group. You can
add the selected disks to an existing disk group or to a new disk group
that will be created as a part of the operation. The selected disks may
also be added to a disk group as spares. Or they may be added as
nohotuses to be excluded from hot-relocation use. The selected
disks may also be initialized without adding them to a disk group
leaving the disks available for use as replacement disks.
More than one disk or pattern may be entered at the prompt. Here are
some disk selection examples:
all: all disks
c3 c4t2: all disks on both controller 3 and controller 4, target 2
c3t4d2: a single disk (in the c#t#d# naming scheme)

You can choose to add this disk to an existing disk group, a
new disk group, or leave the disk available for use by future
add or replacement operations. To create a new disk group,
select a disk group name that does not yet exist. To leave
the disk available for future use, specify a disk group name
of "none".

The selected disks will be added to the disk group rootdg with
disk names that you will specify interactively.

Continue with operation? [y,n,q,?] (default: y)
The following disk device has a valid VTOC, but does not appear to have
been initialized for the Volume Manager. If there is data on the disk
that should NOT be destroyed you should encapsulate the existing disk
partitions as volumes instead of adding the disk as a new disk.
Output format: [Device_Name]

Initializing device c1t2d0.
When selecting the format for the disk, keep in mind that a CDS disk
cannot contain a subdisk for a 'root' or 'swap' volume, so it cannot
be used for mirroring, evacuating, or sparing the boot disk.
