Encrypt single devices using the CLI
Use this procedure to encrypt single devices using the CLI:
Steps
Connect to the SDS node using SSH.
Run the following command to encrypt the new drive.
svm encrypt <device_name>
where
<device_name> is a variable.
For example:
svm encrypt /dev/sdX
or
svm encrypt /dev/nvmeXn0
After about 60 seconds, the new device will be encrypted.
Encrypt multiple devices using the CLI
Use this procedure to encrypt multiple devices using the CLI.
Steps
Connect to the SDS node using SSH.
Encrypt the drives.
SAS-based SSDs:
Select the devices for encryption.
For example,
/dev/sdX, where
X could be a b c - z.
Run the following command:
for i in b c {j..o} {r..v};do svm -y encrypt /dev/sd$i;done
NVMe-based SSDs:
Select the devices for encryption.
For example,
/dev/nvmeXn1, where
X could be 0 1 2 - 24.
Run the following command:
for i in {0..3} 6 7 {10..13} 16 17;do svm -y encrypt /dev/nvme$[i]n1;done
After about 60 seconds, the new device will be encrypted.
