sCfgDskMinFreeBlks
Module: COMTEK-VMS-NM-SYSMGR-MIB
OID (symbolic): COMTEK-VMS-NM-SYSMGR-MIB::sCfgDskMinFreeBlks
OID (numeric): 1.3.6.1.4.1.597.4.3.5.33
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The minimum number of disk blocks that must be free on a disk. When the number of free blocks on a disk drops below this level, excessive disk utilization (sDskFull) traps begin to be sent. If this variable is set to a value other than zero, it is used to determine when to send sDskFull traps for disks not specified in the critical disk table (see sCfgCritDsk).
This value and sCfgDskLimit are mutually exclusive, i.e., only one of these values is in effect at any given time. If neither value is specified in the configuration file, then the default value of sCfgDskLimit is used for disk monitoring and sCfgDskMinFreeBlks is set to zero. To disable default disk full monitoring, both of these values must be zero.
Set-requests to this value will fail unless sCfgDskLimit is set to zero.
Configuration Variable: DskMinFreeBlks Set-requests: Take effect immediately
Changes to this value are written to the sCfgFile.
What is sCfgDskMinFreeBlks?
This is the minimum number of free disk blocks that must remain on a disk before excessive disk utilization traps begin, used as an alternative to the percentage-based sCfgDskLimit and mutually exclusive with it. An administrator sets this when they want an absolute-size threshold, such as ensuring at least a fixed number of blocks stay free regardless of the disk's total capacity. For example, setting sCfgDskMinFreeBlks to a fixed block count on a very large disk would give a more meaningful alert threshold than a percentage would on that disk's scale.
