Deploy Dell PowerFlex v3.6.x

Ensure that the kernel version is correct

Before installing PowerFlex, ensure that the kernel version is correct by performing the following steps.

1. Ensure that your kernel version matches a version in the repository, by performing the following:
   NOTE: If all Ubuntu servers have the same kernel, you can run this command on a single server.
   1. Run this command on every Ubuntu server:

      uname -r

      Output similar to the following is displayed:

      3.16.0-62-generic 

   2. Copy the following text into a browser, and compare the output to the Ubuntu kernel version in the PowerFlex repository:

       ftp://QNzgdxXix:Aw3wFAwAq3@ftp.emc.com

      If your browser blocks links use the following FTP information:

      Link: ftp.emc.com

      Username: QNzgdxXix

      Password: Aw3wFAwAq3

2. To use a mirror repository, you must ensure that the SSH public and SSH private keys are located in all system nodes in the same path.
   The private key should have directory-level permission only (chmod 700 <private_key_path>). The public key can have all permissions. This is not necessary when using the PowerFlex repository.
3. The GPG key must be located in all system nodes in the same path. This key is required for using a mirror or Dell repository.
