Description: Description.
What is hwPerfCacheMirrorWriteUtilization?
This OID reports the percentage of a cache partition occupied by mirrored write cache data, kept in sync with a partner controller for redundancy. An admin monitors this to understand cache pressure from the array's write-mirroring for high availability.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.34774.4.1.21.7.1.4 snmpwalk -v2c -c public <target> ISM-PERFORMANCE-MIB::hwPerfCacheMirrorWriteUtilization
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.34774.4.1.21.7.1.4.1 snmpget -v2c -c public <target> ISM-PERFORMANCE-MIB::hwPerfCacheMirrorWriteUtilization.1
