Apparatus and method for providing upgrade compatibility
An embodiment of the invention provides an apparatus and method that use auto support data for upgrade compatibility. The method includes capturing the input commands that are used by a user (customer) of a storage appliance and that are processed by a current storage operating system in the storage appliance. These input commands are then stored in a database and are the auto support data that is transmitted from the storage appliance via a network to the database. These input commands can be recorded or categorized in the database, based upon the command name or command line arguments of the input commands. These input commands can then be mapped to new input commands that are used with an upgraded storage operating system in a storage appliance. These mapping can be implemented in, for example, a data structure that maps previous input commands to new input commands.
1. A method for providing upgrade compatibility when a storage operating system is upgraded in a storage appliance, the method comprising:
receiving an input command in an interface of a storage appliance, wherein the input command is compatible with a first storage operating system of the storage appliance;
transmitting from the storage appliance the input command via a network to a database;
recording a frequency of the input command in the database;
determining if the frequency of the input command exceeds a threshold frequency; and
if the frequency of the input command exceeds a threshold frequency, then translating the input command to a form compatible with a second storage operating system in the storage appliance, wherein the second storage operating system is an upgrade of the first storage operating system.
2. The method of claim 1 wherein the translating includes utilizing a mapping.
3. The method of claim 1 , further comprising recording in a mapping in the storage appliance each input command in the database based on the frequency of the input command.
4. The method of claim 3 , wherein the translating includes utilizing the mapping.
5. The method of claim 1 , wherein the input command includes a command type.
6. The method of claim 1 , wherein the input command includes a command name.
7. The method of claim 1 , wherein the input command includes a command option.
8. The method of claim 1 , further comprising:
using, by the interface, a mapping to translate the input command.
9. A storage appliance comprising:
a processor;
a memory coupled to the processor;
an interface configured to receive an input command that is compatible with a first storage operating system of the storage appliance, and configured to transmit the input command via a network to a database configured to record a frequency of the input command;
wherein the processor is configured to translate the input command to a form compatible with a second storage operating system in the storage appliance that is an upgrade of the first storage operating system if a frequency of the input command exceeds a threshold frequency.
10. The storage appliance of claim 9 , wherein the memory is configured to store a mapping of the input command into a translation.
11. The storage appliance of claim 10 , wherein the mapping includes a table data structure.
12. The storage appliance of claim 9 , wherein the memory is configured to store a mapping of each input command in the database to a corresponding translation.
13. The storage appliance of claim 9 , wherein the input command includes a command type.
14. The storage appliance of claim 9 , wherein the input command includes a command name.
15. The storage appliance of claim 9 , wherein the input command includes a command option.
16. The storage appliance of claim 9 , further comprising an auto support module configured for communication with the database.
