Example 2: Copying One Logical Volume
|
|
In this example, you are copying only one logical volume (-lv B) from the parent array to
|
the RAID-Copy array.
|
To copy one logical volume, give the commands:
|
|
|
|
|
|
Figure 26. Copying One Logical Volume
|
|
Figure 26 shows, from left to right:
v The parent array that contains the source volume group.
|
v The empty RAID-Copy array coupled to the parent array.
|
v The uncoupled RAID-Copy array that now contains a copy of the logical volume.
|
|
Note that in the copy, all names start with fs.
|
Although the purpose of this job is to copy the logical volume lv_B, by default the
|
ssa_make_copy command has copied the complete contents of hdisk hd_1, which
|
includes the logical volume lv_A. The logical volume fslv_A cannot be accessed,
|
however, because its loglv is on hdisk hd_2 and has not been copied. If a logical
|
volume has its loglv on a separate hdisk, the copy of that logical volume can be
|
accessed only if the hdisk that contains the loglv is also copied.
