Adding a Linux host with IBM Spectrum Symphony to your upgraded cluster

After you have successfully upgraded to IBM® Spectrum Symphony, you can install IBM Spectrum Symphony on additional Linux® hosts, and join the hosts to the upgraded cluster. For any additional hosts, use the same steps as installing IBM Spectrum Symphony to a fresh (not upgraded) host.

About this task

You can add a host to your upgraded cluster at any time; however, a as a best practice, add hosts after you have tested your upgrade, and completed your application upgrade.

Procedure

Install IBM Spectrum Symphony on the host.
- When your cluster is installed to a local file system:
  - Install IBM Spectrum Symphony on a management or compute host. See Installing on a Linux management host or Installing on a Linux compute host.
  - Join the host to the cluster:
```
egoconfig join primary_host
```
- When your cluster is installed to a shared file system, copy the files that set the environment for your management or compute host. See step 10 in Installing to a shared environment.
Verify that the host has joined the cluster:
1. Log on as cluster administrator using the egosh user logon command. For example, to log on using the default Admin user account, enter:
```
egosh user logon -u Admin -x Admin
```
2. Check that the host is running:
```
egosh resource list
```
  Note: It can take a few minutes to show that the newly add host has joined.
