Preparing the drives
This section covers the steps required for preparing new drives to be added to the storage enclosure.
Ensure that the size of the drive and its firmware level match with the drives that are already part of the target
storage enclosure.
Note: To check the drive firmware level, use the following command and check the values in the FW Rev
column:
$ $ n n v v m m e e l l i i s s t t
N N o o d d e e S S N N

You must destroy the existing namespace on the drive and rescan using on of the following options:
Option 1
Use a new storage enclosure.
CAUTION:
Do not attempt this option on the enclosure where you are adding or removing disks. Use a new
enclosure that is not currently in use.
If the disks are part of an existing ThinkAgile CP storage block array, follow these steps to destroy the
namespace:
1. Execute the following command:
# # / / u u s s r r / / s s h h a a r r e e / / t t a a c c p p / / e e n n c c r r y y p p t t i i o o n n / / i i g g n n i i t t e e _ _ b b u u i i l l d d _ _ s s e e d d - - f f - - d d - - v v
2. Rescan the PCI bus by executing the following commands:
m m o o d d p p r r o o b b e e - - r r n n v v m m e e : : e e c c h h o o 1 1 > > / / s s y y s s / / b b u u s s / / p p c c i i / / r r e e s s c c a a n n : : m m o o d d p p r r o o b b e e n n v v m m e e
Option 2
Use this option if you do not have access to another storage enclosure.
1. List all the namespaces on the drive
n n v v m m e e l l i i s s t t - - n n s s / / d d e e v v / / n n v v m m e e 0 0
2. Delete the namespaces
For example, to delete the first namespace use the following command:
n n v v m m e e d d e e l l e e t t e e - - n n s s / / d d e e v v / / n n v v m m e e 0 0 - - n n 1 1
Attention: You must delete all namespaces on all the drives you are installing.
3. Verify that no namespaces exist on the drives:
$ $ n n v v m m e e l l i i s s t t
