The Major Revision level. A change in the major revision level represents a major change in the architecture of the MIB. A change in the major revision level may indicate a significant change in the information supported and/or the meaning of the supported information, correct interpretation of data may require a MIB document with the same major revision level.

The Minor Revision level. A change in the minor revision level may represent some minor additional support; no changes to any pre-existing information has occurred.

A list of RAID controllers managed by the DPT SCSI system.

A set of parameters that describe/control a DPT RAID controller. See 'SmartRAID User's Manual' for detailed explanation of the parameters.

An index that uniquely identifies a row in dptHbaTable that pertains to a particular controller. The value of this object is the logical device identifier for a DPT controller. As controllers are detected, they are assigned numbers incrementally, starting with 0.

The name of the vendor of the controller.

The controller model identifier.

The controller firmware version.

The controller serial number.

The controller Address (normally displayed in hex.) It is a 32-bit value representing the memory address used by the controller

The type of host computer system bus this controller is attached to.

The maximum possible transfer rate on the host bus in MB/s.

The controller interrupt level.

The controller interrupt type (Edge or Level).

The controller DMA channel. This object is only applicable for ISA controllers. Its value is 'notApplicable' for the other types of controllers.

Controller RAID module type: SmartRAID Millennium controllers support all RAID levels without the addition of a RAID Module. These controllers will show 'Embedded' for this object. SmartRAID Decade and Century controllers support RAID 0 and RAID 1 by default. RAID 5 support is added by attaching an RA40x0 RAID Accelerator module to the controller. If one is attached it will be indicated in this object.

The controller caching module. 'Embedded' means that the disk array function is built inside the controller (SmartRAID products.)

This returns the current status of the controller alarm.

Time elapsed (in hundredths of a second) since the controller was last booted.

This indicates whether or not the controller is using DPT ECC memory. 'Yes' means that the installed memory is DPT ECC memory and full ECC protection is active.

This object controls the priority of array background tasks such as Build, Rebuild and Verify for this controller. The values range from 1 to 10. A value of 1 is the slowest but uses the least amount of the controller's bandwidth. While a value of 10 is the fastest but it uses the most bandwidth. If operations take too long then increase the value for this object. If the system runs too slow when these tasks are active, then decrease the value for this object.

Controller exclution period is the time span during which it devotes 100% of its time fulfilling requests for data reads/writes and zero percent on background activities like build/rebuild of arrays. Setting this object to true sets the exclusion period as defined by dptScsiHbaExclusionPeriodStart and dptScsiHbaExclusionPeriodEnd objects. Otherwise, if it is set to false, the exclusion period no effect.

Hour of beginning of the exclusion period. For example, a value of 0 means that the exclusion starts at 12 a.m. The maximum duration of an exclusion period can be 24 hours. Contoller exclution period is the time span during which it devotes 100% of its time fulfilling requests for data reads/writes and zero percent on background activities like build/rebuild of arrays.

Hour when exclusion period ends. For example, a value of 23 means that the exclusion ends at 11 p.m. The maximum duration of an exclusion period can be 24 hours. If dptScsiHbaExclusionPeriodStart is greater than dptScsiHbaExclusionPeriodEnd, it means that the exclusions period extends over the next day. Contoller exclution period is the time span during which it devotes 100% of its time fulfilling requests for data reads/writes and zero percent on background activities like build/rebuild of arrays.

Max percentage of contoller cache RAM devoted to read-ahead pages. This value is not applicable to SmartRAID V and later controllers. For these controllers, this value will be set to 30.

Max percentage of controller cache RAM that may contain dirty pages. This value is not applicable to SmartRAID V and later controllers. For these controllers, this value will be set to 80.

Maximum record size for write caching. This value is not applicable to SmartRAID V and later controllers. For these controllers, this value will be 0.

The write modes are Write-back and Write-through, with write-back being the default. In write-back mode the controller will cache the data and return completion to the host before the data is written to disk. This is the highest performance mode. In write-through mode the controller will always write the data to disk before posting complete to the host. The data may or may not be placed into the controller's cache.

Indicates whether the device has reported a SMART error not (not applicable to logical devices).

A list of RAID array groups.

These parameters describe/control a RAID array group.

The RAID type for the Logical Drive. ------------------------------ RAID Disk-fault No.of Level Tolerant Drives ------------------------------ RAID-0 No 2 or more RAID-1 Yes Even number RAID-5 Yes 3 or more Hot Spare - one Redirected - one

software entity that created this logical device.

Name of the RAID array group.

Percentage of completion of an outstanding background operation, e.g., array Build, Rebuild or Verify. If there is no current background process, the value is 100 by default.

- 'active': indicates that the table row is available for use by the managed device; - 'notInService': indicates that the table row exists in the agent, but is unavailable for use by the managed device (see NOTE below); - 'notReady': indicates that the table row exists in the agent, but is missing information necessary in order to be available for use by the managed device; - 'createAndGo': supplied by a management station wishing to create a new instance of a table row and to have it available for use by the managed device; (cannot be returned in a get response) - 'createAndWait': supplied by a management station wishing to create a new instance of a table row but not to have it available for use by the managed device; and, (cannot be returned in a get response) - 'destroy': supplied by a management station wishing to delete all of the objects associated with an existing table row. (cannot be returned in a get response) To create new row, a manager sets this object to createAndWait. Agent creates a new row and sets row status to notInService. After the manager creates all the corresponding rows in dptScsiArrMemberTable and has set all the relevant columnar objects, it finally sets dptScsiArrEntryStatus to active which saves all the information to the hardware and performs an array build. If the manager sets dptScsiArrEntryStatus to active or notInService and the required number of drives are not members of this array group (for example, a RAID-5 needs at least 3 drives), then 'inconsistentValue' is returned. To delete an array group, the manager sets this object to destroy. When a row with a particular row index is destroyed, all corresponding rows in dptScsiArrMemberTable are destroyed as well. +---------------+ +--------------+ +--------+ | doesn't exist | --> | notInService | --> | active | +---------------+ +--------------+ +--------+ Array group is Array group is Array group is not created created in the saved to hardware agent and a build is performed

A list of mappings between an array device and its components.

These parameters describe/control the mappings between an array and its components. In the index clause, the first set of indices from dptScsiHbaNumber to dptScsiDevLevel describes the array (parent) and the second set represents the member (child).

The stripe size used by the array (in KB). A stripe is a contiguous region for data storage on a disk. Data is distributed evenly across component drives in an array by concatenating interleaved stripes from each drive. If stripe size is not applicable to a particular type of RAID (e.g., hot spare), the value is 0.

To create a new row, manager sets this object to createAndWait. After successful creation of a row in the agent, it is set to notInService until the parent array is made active and at that time it is set to active as well. Setting it to createAndGo has the same effect as that of createAndWait. +---------------+ +--------------+ +--------+ | doesn't exist | --> | notInService | --> | active | +---------------+ +--------------+ +--------+ A new row is Array group is created in the saved to hardware agent and a build is performed

A list of controller statistics.

These parameters describe the statistics of an controller.

Auxiliary voltage status reported by the controller.

An index that uniquely identifies a row in the dptHbaTable table that pertain to a particular HBA. The value of this object is the logical device identifier for a DPT adapter. In EISA systems, EISA bus slots are scanned, starting from the lowest slot, looking for DPT adapters. In ISA system, DPT adapters are scanned in order of I/O address. As DPT adapters are found, they are assigned numbers incrementally, starting with 0.

Indicates whether the device is a physical device (level 0) or a logical device (level 1, level 2, etc). It also gives its level in the containment hierarchy of devices. A device is a logical device if it contains other SCSI devices, otherwise it is a physical device. A level 1 array contains only physical devices as its members; a level 2 device has at least one level 1 array as a member; and so on. In the case of HBA with no RAID capabilities, the only applicable device level is 0.
