Simplified setup: Doing other tasks

Learn how to do other tasks after you complete the simplified setup.

About this task

For the first three tasks in this topic, you need the password for your SKLM key server.

Adding a node to the cluster

Procedure

When you add a node to a cluster that is configured for encryption by the simplified setup, the cluster automatically detects the node and copies the encryption configuration to it. To encrypt files, the node must have direct network access to the Remote Key Management (RKM) server. For more information, see the section "Requirements" in the topic Preparation for encryption.

Creating encryption keys

Procedure

This task shows how to create encryption keys in a tenant:

  1. The following command creates five encryption keys in tenant devG1 on key server keyserver01 and displays the UUIDs of the keys on the console: 
     mmkeyserv key create --server keyserver01.gpfs.net --tenant devG1 --count 5
Enter password for the key server keyserver01.gpfs.net:
KEY-492911c8-e3d4-4670-9868-617243d4ca57
KEY-5f24d71f-daf3-4df8-90e4-5f6475370f70
KEY-a487b01d-f092-4895-b537-139edeb57239

KEY-fd3dbee9-0e6c-4662-9410-bfe3b73272b9
    The command displays the UUIDs of the previously existing key and the five new keys.

Adding a tenant to GKLM

About this task

A tenant is a container that resides on a key server and contains encryption keys. Before a key client can request master encryption keys from a key server, you must add a tenant to the key server, create a key client, and register the key client with the tenant. For more information, see Simplified setup: Using SKLM with a self-signed certificate.

In some situations, you might need to access more than one tenant on the same key server. For example, if you have several key clients that you want to use with the same key server, each key client must register with a different tenant. For more information, see Simplified setup: Valid and invalid configurations.

This task shows how to add a tenant, register an existing key client with the tenant, and create encryption keys in the tenant.

Procedure

  1. Add the tenant:
    1. Add a tenant devG2 on keyserver01: 
       mmkeyserv tenant add devG2 --server keyserver01
Enter password for the key server keyserver01:
    2. Verify that the tenant is added. The following command displays all the existing tenants: 
       mmkeyserv tenant show
devG1
        Key Server:          keyserver01.gpfs.net
        Registered Client:   c1Client1

devG2
        Key Server:          keyserver01.gpfs.net
        Registered Client:   (none)
      The tenants are devG1 and devG2.
  2. Register the existing key client with the tenant:
    1. Register client c1Client1 with tenant devG2: 
       mmkeyserv client register c1Client1 --tenant devG2 --rkm-id keyserver01_devG2
Enter password for the key server :
mmkeyserv: [I] Client currently does not have access to the key. 
Continue the registration process...
mmkeyserv: Successfully accepted client certificate
    2. Verify that the key client is registered to the tenant: 
       mmkeyserv client show
c1Client1
        Label:               c1Client1
        Key Server:          keyserver01.gpfs.net
        Tenants:             devG1,devG2
      The command output shows that c1Client1 is registered to both devG1 and the new devG2.
    3. Verify the configuration of the RKM stanza. The following command displays all the RKM stanzas: 
       mmkeyserv rkm show 
keyserver01_devG1 {
  type = ISKLM
  kmipServerUri = tls://192.168.40.59:5696
  keyStore = /var/mmfs/ssl/keyServ/serverKmip.1_keyserver01.c1Client1.1.p12
  passphrase = pw_c1Client1
  clientCertLabel = label_c1Client1
  tenantName = devG1
}
keyserver01_devG2 {
  type = ISKLM
  kmipServerUri = tls://192.168.40.59:5696
  keyStore = /var/mmfs/ssl/keyServ/serverKmip.1_keyserver01.c1Client1.1.p12
  passphrase = pw_c1Client1
  clientCertLabel = label_c1Client1
  tenantName = devG2
}
      The command shows the following relationships:
      • Client c1Client1 is registered with tenant devG1 on keyserver01.
      • Client c1Client1 is also registered with tenant devG2 on keyserver01.
  3. Create keys in the tenant.
    The following command creates three keys in tenant devG2:
     mmkeyserv key create --server keyserver01 --tenant devG2 --count 3
Enter password for the key server keyserver01:
KEY-43cf5e69-1640-4056-b114-bdbcf2914189
KEY-4c7540cd-0346-4733-90eb-8df4c0f16008
KEY-c86a523b-e04f-4536-86a6-c6f83f845265

Adding backup key servers

About this task

If multiple key servers exist, you can add them to an RKM stanza to provide backup capability in case the main key server becomes unavailable. You can add up to five backup key servers.

Important: IBM Storage Scale does not manage backup key servers. You must configure them and maintain them.
Note: For information about using backup key servers, see the subtopic "Adding backup RKM servers in a high-availability configuration" in Preparation for encryption.

This task shows how to add backup key servers to the RKM stanza of one of your key clients. You can add backup key servers when you create a key server, as shown in Step 2 of the previous subtopic. Or you can add them later, as in this subtopic.

In this task the primary key server is keyserver11. The backup key servers for the RKM stanza are keyserver12 and keyserver13. You want to add three more backup key servers to the list: keyserver14, keyserver15, and keyserver16.

Procedure

Follow these steps:

  1. Add the three backup key servers. You must specify the entire list of key servers, including ones that are already in the list. The following command is on one line. In the list of servers, do not put spaces on either side of the commas (,): 
     mmkeyserv rkm change keyserver11_devG1 --backup 
keyserver12,keyserver13,keyserver14,keyserver15,keyserver16
    Attention:
    • You can change the order in which the client tries backup key servers, by running the same command with the key servers in a different order.
    • You can delete backup key servers by specifying a list that contains the backup key servers that you want to keep and omits the ones that you want to delete.
  2. To verify, issue the mmkeyserv rkm show command to display the RKM stanzas: 
     mmkeyserv rkm show
keyserver01_devG1 {
  type = ISKLM
  kmipServerUri = tls://192.168.40.59:5696
  keyStore = /var/mmfs/ssl/keyServ/serverKmip.1_keyserver01.c1Client1.1.p12
  passphrase = pw4c1Client1
  clientCertLabel = c1Client1
  tenantName = devG1
}

keyserver01_devG2 {
  type = ISKLM
  kmipServerUri = tls://192.168.40.59:5696
  keyStore = /var/mmfs/ssl/keyServ/serverKmip.1_keyserver01.c1Client1.1.p12
  passphrase = pw4c1Client1
  clientCertLabel = c1Client1
  tenantName = devG2
}

keyserver11_devG1 {
  type = ISKLM
  kmipServerUri = tls://keyserver11.gpfs.net:5696
  kmipServerUri12 = tls://keyserver12.gpfs.net:5696
  kmipServerUri13 = tls://keyserver13.gpfs.net:5696
  kmipServerUri14 = tls://keyserver14.gpfs.net:5696
  kmipServerUri15 = tls://keyserver15.gpfs.net:5696
  kmipServerUri16 = tls://keyserver16.gpfs.net:5696
  keyStore = /var/mmfs/ssl/keyServ/serverKmip.2_keyserver11.c1Client11.1.p12
  passphrase = pw4c1Client11
  clientCertLabel = c1Client11
  tenantName = devG1
}
    The command output shows the following relationships:
    • The configuration of c1Client1, devG1, and keyserver01 has zero backup servers.
    • The configuration of c1Client1, devG2, and keyserver01 has zero backup servers.
    • The configuration of c1Client11, devG1, and keyserver11 has five backup servers.

Adding a role or scope to Vault

About this task

Within an IBM Storage Scale cluster, only one role can be created per scope. The mmkeyserv role create command creates a scope and a role at the same time.

Procedure

Follow these steps:

  1. Create the role.
    1. Create a scope spectrumscale2 and a role gpfsAdmin2: 
       mmkeyserv role create gpfsAdmin2 --scope spectrumscale2 --server tru-4pub --auth-token tempToken
Create a pass phrase for keystore: 
Confirm your pass phrase: 
mmkeyserv: Propagating the cluster configuration data to all
  affected nodes.  This is an asynchronous process.
    2. To verify the scope and role are created, issue the following command: 
      
mmkeyserv role show gpfsAdmin2
gpfsAdmin2

  2. Register the new role.
    1. Register role gpfsAdmin2: 
       mmkeyserv role register gpfsAdmin2 --rkm-id gpfsRKMstanza2
mmkeyserv: Propagating the cluster configuration data to all
  affected nodes.  This is an asynchronous process.
    2. Verify that the role is registered: 
       mmkeyserv role show gpfsAdmin2
gpfsAdmin2

    3. Verify the configuration of the RKM stanza. The following command displays all the RKM stanzas: 
       mmkeyserv rkm show
gpfsRKMstanza {
  type = KMIP
  kmipServerUri = tls://9.46.79.137:5696
  keyStore = /var/mmfs/ssl/keyServ/roleCred.1_gpfsAdmin.1.p12
  passphrase = pass!@#ForDemo
  clientCertLabel = 1_gpfsAdmin
}
gpfsRKMstanza2 {
  type = KMIP
  kmipServerUri = tls://9.46.79.137:5696
  keyStore = /var/mmfs/ssl/keyServ/roleCred.4_gpfsAdmin2.1.p12
  passphrase = pass!@#4admin2
  clientCertLabel = 4_gpfsAdmin2
  connectionTimeout = 15
  connectionAttempts = 4
  retrySleep = 5000
}
  3. Create a key from new role. 
     mmkeyserv key create --role gpfsAdmin2
