h3cDiskWriteCache
Module: H3C-DISK-MIB
OID (symbolic): H3C-DISK-MIB::h3cDiskWriteCache
OID (numeric): 1.3.6.1.4.1.2011.10.10.3.1.1.1.13
Node type: OBJECT-TYPE
Type: H3cStorageEnableState
Access: read-write
Description: This object identifies the state of write cache.
What is h3cDiskWriteCache?
This read-write value enables or disables write caching for this disk. Admins weigh enabling it for better write performance against the added risk of data loss on power failure if writes are cached but not yet committed to the physical medium. For example, an admin in an environment without reliable battery-backed cache protection might set this to disable to prioritize data safety over write throughput.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.10.10.3.1.1.1.13 snmpwalk -v2c -c public <target> H3C-DISK-MIB::h3cDiskWriteCache
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.10.10.3.1.1.1.13.1 snmpget -v2c -c public <target> H3C-DISK-MIB::h3cDiskWriteCache.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2011.10.10.3.1.1.1.13.1 s <value>
