Description: SCSI Device Negotiated Period.
This is the amount of time that was negotiated between the controller and the device as a synchronous transfer window. A synchronous transfer window is how long the device can transfer data without requiring an acknowledgment from the controller. In general the larger the negotiated period is, the lower the device throughput. This value is reported in quarters of nanoseconds.
What is cpqScsiTargetNegPeriod?
This integer reports the synchronous transfer window negotiated between the controller and this target, in quarters of nanoseconds, where a larger period generally means lower throughput. Admins use it to understand why a given device's data transfer speed seems slow compared to others on the same bus. For example, a target showing an unusually large negPeriod compared to its peers would explain why it's the slowest device on that channel.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.5.2.5.1.1.12 snmpwalk -v2c -c public <target> CPQSCSI-MIB::cpqScsiTargetNegPeriod
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.5.2.5.1.1.12.1 snmpget -v2c -c public <target> CPQSCSI-MIB::cpqScsiTargetNegPeriod.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cpqScsiTargetNegPeriod.1
