Method for implementing on demand configuration changes

A storage controller comprising a computer readable medium comprising computer readable program code encoded therein to reconfigure a logical storage volume, the computer readable program code comprising a series of computer readable program steps to effect:

• determining if utilization of said logical storage volume is nearing capacity;
• operative if utilization of said logical storage volume is nearing capacity, determining if configured physical storage space is available;
• operative if configured physical storage space is available, reconfiguring said logical storage volume using all or a portion of said configured physical space;
• wherein the computer readable program code to determine if a storage capacity of the logical storage volume is nearing capacity further comprises a series of computer readable program steps to effect:
• establishing a logical volume utilization threshold;
• determining an actual logical volume utilization;
• operative if said actual logical volume utilization is greater than said logical volume utilization threshold, determining that said logical storage volume is nearing capacity.

A computer program product encoded in a computer readable medium and useable with a programmable computer processor to reconfigure a logical storage volume, the computer program product comprising:

• computer readable program code which causes said programmable processor to determine if a storage capacity of said logical storage volume is nearing capacity;
• computer readable program code which, if said storage capacity of the logical storage volume is nearing capacity, causes said programmable processor to determine if configured physical storage space is available;
• computer readable program code which, if configured physical storage space is available, causes said programmable processor to re-configure said logical volume to include all or a portion of said configured physical space;
• wherein the computer readable program code to determine if a storage capacity of the logical storage volume is nearing capacity further comprises:
• computer readable program code which causes said programmable processor to retrieve a pre-determined logical volume utilization threshold;
• computer readable program code which causes said programmable processor to determine an actual logical volume utilization;
• computer readable program code which, if said actual logical volume utilization is greater than said logical volume utilization threshold, causes said programmable processor to determine if configured physical storage space is available.
