Automation Command

 

 

 

Description

 

 

 

Journal <Vol #> {01}

 

Enables (1) or disables journaling for specified volume.

AddJournal <Vol #> [ <Journal

 

Creates a journal for the given volume number (For file-

 

based

journal: raid.addjournal 0 i:\c0d0j1.jrn;

for in-

file> ]

 

 

memory journal: raid.addjournal 0).

 

 

 

 

 

 

 

 

 

ResizeJournal <Vol #> [ <Old

 

Resizes the journal for the given volume to the new

Journal> <New Journal> ]

 

journal parameters.

 

 

 

 

Commit <Vol #>

 

Commit copies back the modified data blocks from the

 

journal to the disk image and clears the journals.

 

 

 

 

 

Clear <Vol #>

 

Clears the volume - discards any changes made to the

 

volume.

 

 

 

 

 

 

 

 

 

 

 

 

 

Flatten <Vol #>

 

Deletes the journal added last for that particular volume.

 

 

 

Displays the status for the RAID device or a particular

 

 

 

volume. -v option displays details regarding the

Status [ <Vol #> ] [-v -r]

 

statistics of performance meters implemented in the

 

 

 

RAID device, while -r option resets the performance

 

 

 

counters.

 

 

 

 

 

SetDBC <Entries> <Depth>

 

Set the parameters for disk block cache (For e.g.,

<Block Size>

 

raid.setdbc 32768 5 512.

 

 

 

SetJournalParameters <Super Block

 

Set

the

Journal

Parameters

(For

e.g.,

Size> <Index Block Size> <Index

 

raid.setjournalparameters 8192 512 3 512).

 

Levels> <DiskBlock Size>

 

 

 

 

 

 

 

 

GetJournalParameters

 

Displays the Journal parameters.

Automation Command

 

 

 

Description

 

 

 

 

 

 

Enables (1) or disables (0) the PDL Error Simulation. If

PdlErrorSim (01)

 

enabled then the DIMM device monitors PDL settings

 

 

 

for all RAM reads.

 

 

 

 

GetPdlErrorSim

 

Returns enabled if PdlErrorSim is enabled; otherwise it

 

returns disabled.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The „Out of Range Response‟ selection specifies how

 

 

 

the data should be altered if a PDL is out of range. The

OutOfRangeResp (0xFF invert)

 

0xFF option

specifies

that the return

data should be

 

forced to all ones. The Invert option specifies that the

 

 

 

 

 

 

return data should be a bitwise inversion of the valid

 

 

 

data.

 

 

 

 

 

 

GetOutOfRangeResp

 

Returns the specified options set by OutOfRangeResp.

 

 

 

The SMB Base Address entry selects the 8-bit address

SMBBaseAddr <addr>

 

that this DIMM device responds to. The SMB address is

 

 

 

used for the reading of DIMM SPD data.

 

 

 

GetSMBBase

 

Returns the specified SMB Base address.

 

 

 

 

ImportSPD provides the option of loading SPD ROM

ImportSPD <DimmNo> <fullpath>

data to DimmNo from the file specified by “fullpath”.

The file format is an unformatted binary image, with an

 

 

extension of “.spd”.
