Description: Cisco UCS storage:EnclosureLocalDiskConfig:physicalBlockSize managed object property
What is cucsStorageEnclosureLocalDiskConfigPhysicalBlockSize?
This reports the physical block (sector) size, in bytes, that the local disk in this EnclosureLocalDiskConfig record actually uses at the hardware level. An admin or storage controller compares this to the disk's logical block size to detect 512e/4Kn formatting differences that can affect RAID alignment and performance. A disk reporting a 4096-byte physical block size mixed into an enclosure of otherwise 512-byte disks is the kind of mismatch this field would surface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.45.111.1.16 snmpwalk -v2c -c public <target> CISCO-UNIFIED-COMPUTING-STORAGE-MIB::cucsStorageEnclosureLocalDiskConfigPhysicalBlockSize
Get a specific instance (index 1):

SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cucsStorageEnclosureLocalDiskConfigPhysicalBlockSize.1
