Changing a mode of a storage subsystem in a system
First Claim
1. A method for use in a system having a storage subsystem capable of being set in at least a first mode and a second mode, comprising:
- operating the storage subsystem in the first mode, wherein redundant information is stored in a first portion of the storage subsystem in the first mode;
receiving an indication to indicate that a mode of the storage subsystem is to be changed from the first mode to the second mode;
in response to the indication, changing the mode of the storage subsystem from the first mode to the second mode; and
storing non-redundant information in the first portion of the storage subsystem in the second mode, wherein changing the mode of the storage subsystem is performed without resetting the system.

Abstract
A system includes a storage subsystem capable of being set in at least a first mode and a second mode. When operating the storage subsystem in the first mode, redundant information is stored in a first portion of the storage subsystem in the first mode. An indication is received to indicate that a mode of the storage subsystem is to be changed from the first mode to the second mode. In response to the indication, the mode of the storage subsystem is changed from the first mode to the second mode. In the second mode, non-redundant information is stored in the first portion of the storage subsystem. The mode of the storage subsystem is changed without resetting the system.

17. A system comprising:
-
a memory subsystem having plural fault tolerant modes, wherein the memory subsystem has memory slots, and at least one memory module insertable in one of the memory slots; and
a routine executable in response to detecting insertion of the memory module in the one memory slot, the routine to change the fault tolerant mode of the memory subsystem to change a storage capacity of the memory subsystem. - View Dependent Claims (18, 19, 20, 21, 22)

23. A system comprising:
-
a processor;
a storage adapted to be set to one of plural fault tolerant modes, the fault tolerant modes comprising first and second fault tolerant modes, the first fault tolerant mode associated with a first storage capacity, and the second fault tolerant mode associated with a second, larger storage capacity; and
a routine executable on the processor to change the fault tolerant mode of the storage from the first fault tolerant mode to the second fault tolerant mode to increase storage capacity in response to receiving a user-activated input, wherein the routine is executable to change the fault tolerant mode of the storage from the first fault tolerant mode to the second fault tolerant mode without resetting the system. - View Dependent Claims (24, 25, 26)

27. An article comprising at least one storage medium containing instructions for setting a mode of a memory subsystem, the instructions when executed causing a system to:
-
receive an indication to indicate the mode of the memory subsystem is to be changed from a first mode to a second mode, wherein a first portion of the memory subsystem is for storing redundant information in the first mode; and
in response to the indication, configure the memory subsystem to operate in the second mode, wherein the first portion of the memory subsystem is for storing non-redundant information in the second mode, wherein the receiving and configuring are performed without resetting the system. - View Dependent Claims (28, 29, 30, 31, 32)
