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 nvvm mee lliisstt
NNooddee SSNN MMooddeell NNaam meessppaaccee UUssaaggee FFoorrm maatt FFWW RReevv

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 ussrr//ssh haarree//ttaaccp p//een nccrryyp pttiio on n//iig gn niittee__b bu uiilld d__sseed d --ff --d d --vv
2. Rescan the PCI bus by executing the following commands:
m mo od dp prro ob bee --rr n nvvm mee::eecch ho o 1 1 > > //ssyyss//b bu uss//p pccii//rreessccaan n::m mo od dp prro ob bee n nvvm mee
Option 2
Use this option if you do not have access to another storage enclosure.
1. List all the namespaces on the drive
n nvvm mee lliisstt--n nss //d deevv//n nvvm mee0 0
2. Delete the namespaces
For example, to delete the first namespace use the following command:
n nvvm mee d deelleettee--n nss //d deevv//n nvvm mee0 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 nvvm mee lliisstt
