Configuring HMC

HMC or Harware Management Console, is now an integral part of Iseries system. This has two standard models:-
1- The desktop model, it has only one Ethernet port.
2- Rack model , it has two standard Ethernet port.

Once, a new system is purchased, it comes with HMC, the HMC software is pre-loaded and also a CD is shipped for recovery purpose. Once, HMC is connected to the system. The procedure that you need to follow to configure HMC is as below,

1- Managed System Powered off.
2- Power on HMC
2- Login as hscroot or root with default password (hsroot = abc123, root = passw0rd)
3- Set date and time
4- Change default password for hscroot and root
5- Create additional user profile's to access HMC
6- Configure HMC network connection
7- Configure HMC to connect to network provider
8- Reboot HMC
9- Check HMC software version

If this is a new HMC , you will automatically be prompted to Guided setup, after you power on the HMC. Once, you switch on the power switch. You can see the initialization messages on your screen. After, this it will prompt you to login with a user name and password. Use hscroot or root user id. This will take you to the screen to set date and time.

On a new HMC change the default passwords. If you wish to create more user profiles, then the required screen will have new user id tab, new password and re-enter new password tab along with roles  tab , in which you have option to choose from below roles,
1- HMCSERVICEREP
2- HMCVIEWER
3- HMCOPERATOR
4- HMCPE
5- HMCSUPERADMIN

1- HMCSERVICEREP - hmcservicerep is a service representative id for IBM support personnel to access HMC.

2- HMCVIEWER - the user can only view HMC information, but has no authority to modify or change HMC options.

3- HMCOPERATOR - this user can perform daily tasks, but do not have authority to add new users or modify the roles.

4- HMCPE - Product engineer and service representative can perfom almost every task. However, PE can additionally shut down HMC and close virtual terminal windows which service representative cannot do.

5- HMCSUPERADMIN - Super admin has same authority as the hscroot or root. They have all the access to HMC and can manage and modify almost everything in HMC.
.
Once you have completed adding users, it will prompt you to configure the network Settings. I will discuss about this tomorrow in my next post.
