Abstract

A system, method and program product for for automatically configuring a storage device for a server. A method is provided that includes:preconfiguring the storage device with a set of LUNs and a hostgroup; preconfiguring the server to include a storage configuration package; connecting the storage device to the server; launching the storage configuration package on the server to run a set of scripts to perform the actions comprised of: installing a set of drivers; resetting a UUID and modifying a kernel; installing a storage management system on the server; discover WWIDs, a hostname and the storage device; create and add the hostname to the hostgroup; and pass the WWIDs to the storage device; and mapping a set of disks; and rebooting the computer.

Claims

1. A method for automatically configuring a storage device for a host, comprising:

preconfiguring the storage device with a set of LUNs (logical unit numbers) and a hostgroup;

preconfiguring the host to include a storage configuration package;

connecting the storage device to the host;

launching the storage configuration package on the host to run a set of scripts to perform the actions comprised of;

installing a set of drivers;

resetting a UUID (universally unique identifier) and modifying a kernel;

installing a storage management system on the host;

discovering WWIDs (world wide identifiers), a hostname and the storage device;

creating and adding the hostname to the hostgroup;

passing the WWIDs to the storage device, and associating the WWIDs with the host;

mapping a set of disks; and

rebooting the host.

2. The method of claim 1, wherein all communication between the host and storage device is performed in-band.

3. The method of claim 1, wherein the set of drivers allow the host to communicate with the storage device.

4. The method of claim 1, wherein the hostgroup is empty when the storage device is preconfigured.

5. The method of claim 1, wherein the storage management system is utilized to administer the storage device.

6. The method of claim 1, wherein the WWIDs comprise unique identifiers of ports on a storage controller of the host.

7. A system for automatically configuring a storage device for a host, comprising:

a system for automatically installing a set of drivers on a host;

a system for automatically resetting a UUID (universally unique identifier) and modifying a kernel;

a system for automatically installing a storage management system on the host;

a system for automatically discovering WWIDs (world wide identifiers), a hostname and the storage device;

a system for automatically creating and adding the hostname to the hostgroup, and for automatically passing the WWIDs to the storage device; and

a system for automatically mapping a set of disks and rebooting the host.

8. The system of claim 7, wherein all communication between the host and storage device is performed in band.

9. The system of claim 7, wherein the set of drivers allow the host to communicate with the storage device.

10. The system of claim 7, wherein the hostgroup is initially empty after the storage device is preconfigured.

11. The system of claim 7, wherein the storage management system is utilized to administer the storage device.

12. The system of claim 7, wherein the WWIDs comprise unique identifiers of ports on a storage controller of the host.

13. A computer readable storage medium having a program product stored thereon for automatically configuring a host for a storage device, which when executed by a computer system includes:

program code for automatically installing a set of drivers on a host;

program code for automatically resetting a UUID (universally unique identifier) and modifying a kernel;

program code for automatically installing a storage management system on the host;

program code for automatically discovering WWIDs (world wide identifiers), a hostname and the storage device;

program code for automatically creating and adding the hostname to the hostgroup and for automatically passing the WWIDs to the storage device; and

program code for automatically mapping a set of disks and rebooting the host.

14. The computer readable storage medium of claim 13, wherein all communication between the host and storage device is performed in-band.

15. The computer readable storage medium of claim 13, wherein the set of drivers allow the host to communicate with the storage device.

16. The computer readable storage medium of claim 13, wherein the hostgroup is initially empty after the storage device is preconfigured.

17. The computer readable storage medium of claim 13, wherein the storage management system is utilized to administer the storage device.

18. The computer readable storage medium of claim 13, wherein the WWIDs comprise unique identifiers of ports on a storage controller of the host.

19. A method for deploying a system for automatically configuring a host for a storage device, comprising:

providing a computer infrastructure being operable to;

automatically install a set of drivers on a host;

automatically reset a UUID and modify a kernel;

automatically install a storage management system on the host;

automatically discover WWIDs (world wide identifiers), a hostname and the storage device;

automatically create and add the hostname to the hostgroup;

automatically pass the WWIDs to the storage device; and

automatically map a set of disks and reboot the host.

20. The method of claim 19, wherein the hostgroup is initially empty.
