Antivirus scan during a data scrub operation
View Patent ↗For an antivirus scan during a data scrub operation, an antivirus scan is concurrently performed as an overlap with the data scrub operation, wherein the data scrub operation periodically inspects and corrects memory errors. The antivirus scan concurrently performing as an overlap with the data scrub operation is increased if a reduction in disk access by a host application is detected. A number of antivirus scan input/output (I/O) operations and data scrub I/O operations is reduced.
1. A method for an antivirus scan during a data scrub operation by a processor device in a computing environment, the method comprising:
concurrently performing the antivirus scan as an overlap with the data scrub operation, wherein the data scrub operation periodically inspects and corrects memory errors,
increasing the antivirus scan concurrently performing as an overlap with the data scrub operation if a reduction in disk access by a host application is detected, and
reducing a number of antivirus scan input/output (I/O) operations and data scrub I/O operations.
2. The method of claim 1 , further including performing one of:
allowing for an increased number of host input/output (I/O) operations from a host while concurrently performing the antivirus scan with the data scrub operations, and
performing the antivirus scan as an overlap with the data scrub operation in a data storage system configured with a redundant array of independent disks (RAID).
3. The method of claim 1 , further including, in conjunction with the performing, overlapping the antivirus scan with an XORing operation of data to compare a parity of the data during a cycle of the data scrub operation.
4. The method of claim 1 , further including, concurrently performing the antivirus scan upon detecting an uncorrectable data error during a background task of the data scrub operation.
5. The method of claim 1 , wherein the antivirus scan and data scrub operation are performed during idle time.
6. The method of claim 1 , further including, increasing the performing the antivirus scan as an overlap with the data scrub operation during periods of a reduction in disk access by a host application.
7. The method of claim 1 , wherein the antivirus scan includes performing at least one of scanning data for malicious code, virus scanning, and content scanning.
