Remove A Raid 1 Component (Remove A Mirror Drive); Replace A Logical Drive; The Different States Of An Array Drive - ICP RS Series User Manual

To avoid that problem, you can mirror in a first step a new good Logical Drive to the critical
one. When the copying is finished you remove the critical Logical Drive and then carry out a
hot plug procedure.
To add a RAID 1 component you need to select in a first step a Logical Drive, the master.
All suitable Logical Drives (with a capacity equal of larger than the capacity of the master)
are shown in a box. Now choose the Logical Drive you want to add, the slave. After con-
firming, a new RAID 1 Array Drive is build, i.e., all data from the master are copied to the
slave drive(s). When this process is finished all Logical Drives in the RAID 1 Array Drive are
identical (there is no longer a difference between master and slave).
K.5.15 Remove a RAID 1 Component (Remove a Mirror Drive)
Click the right mouse button on the Logical Drive icon.
Here you can remove a drive from a RAID 1 Array Drive. If the Array Drive is in the build or
in the fail state, you may only remove invalid RAID 1 components.
To remove a Logical Drive from a RAID 1 Array Drive you have to select the Logical Drive
you want to remove. This is done by selecting a Logical Drive from a box where you see all
members of the RAID 1 Array Drive . After confirmation the Logical Drive is removed. If the
RAID 1 Array Drive consists of two drives (like usual) the RAID 1 Array Drive disappears and
only one Logical Drive will be left. You can create a new RAID 1 Array Drive by selecting add
RAID 1.
K.5.16 Replace a Logical Drive
Click the right mouse button on the Logical Drive icon.
If a Logical Drive of an Array Drive without a Hot Fix Drive should fail (or is very likely to
fail, soon), you should replace the defective hard disk with a new one as soon as possible,
because the Array Drive is without redundancy. The replacement Logical Drive has to have
at least the same capacity as the failed one. The replacement is carried out with ICPCON or
the ICP RAID Navigator. Before the Logical Drive can be removed, you have to select a new
Logical Drive from the box with available Physical Drives which is shown after this option is
selected. If no Physical Drive is offered, you have to use the Hot Plug: Replace Drive func-
tion to add a new drive. After the confirmation, the old Logical Drive is removed. Next, the
data is rebuild on the new Logical Drive. During this process the array is in the rebuild state
and therefore not redundant.
