These are the compliance rules for the Automatic Storage Management (ASM) compliance standards. The compliance standards are:
The compliance rules for the Storage Best Practices for ASM compliance standard follow.
Description: Checks the disk group, with NORMAL or HIGH redundancy, for disks that are mirrored or parity protected.
Severity: Minor Warning
Rationale: Disk resources are wasted, and performance may be unnecessarily affected when both a disk and its owning disk group are providing data redundancy.
Description: Checks the disk group, which depends on external redundancy, for disks that are not mirrored or parity protected.
Rationale: Data loss can occur if the disk group depends on external redundancy and disks are not mirrored or parity protected.
Description: Checks the disk group for disks that have different redundancy attributes.
Rationale: Disks in the same disk group with different redundancy attributes may offer inconsistent levels of data protection.
Description: Checks the disk group for disks with disk sizes which vary by more than 5%.
Rationale: Disks in a disk group should have sizes within 5% of each other, unless data migration is in progress. Automatic Storage Management distributes data uniformly proportional to the size of the disks. For balanced I/O and optimal performance, disks in a given disk group should have similar size and performance characteristics.
The compliance rule for the Patchable Configuration for ASM compliance standard follows.
