58 MDR User Guide
Considering the two configuration parameters of the reset command (jumper and <Re-
setType
> parameter of the reset command), there are six different reset cases:
• Jumper setting: in (default MDR configuration)
• Pushing the reset button on the front panel will reset the MDR system but not the
other boards present on the same VME backplane,
• Executing the ‘
ResetServer(MDR_RESET_VME)’ function from the MDR Shell
will have no effect at all on the MDR Server(s),
• Executing the ‘R
esetServer(MDR_RESET_I960)’ function from the MDR Shell
will reset the MDR system but not the other boards present on the same VME
backplane,
• Jumper setting: out
• Pushing the reset button on the front panel will reset the MDR system and the
other boards present on the same VME backplane,
• Executing the ‘
ResetServer(MDR_RESET_VME)’ command from the MDR Shell
will have exactly the same effect as pushing the front panel reset button,
• Executing the ‘
ResetServer(MDR_RESET_I960)’ command from the MDR
Shell will reset the MDR system but not the other boards present on the same
VME backplane.
Scan
Declaration:
STATUS Scan (DISK_INFO * DiskInfoTbl,
UINT DiskInfoTblSize,
UINT * DisksFound,
DISK_GROUP_INFO * DiskGroupInfoTbl,
UINT DiskGroupInfoTblSize,
UINT * DiskGroupsFound,
UINT Options);
Description: Scan for new disk and/or disk groups.
This function scans for new Fibre Channel devices: disks and/or disk groups and returns
the gathered information in the
DiskInfoTbl, DisksFound, DiskGroupInfoTbl and
DiskGroupsFound parameters.
The
Options parameter specifies which MDR actor (Client and/or Server) should
perform the scan operation:
•
MDR_DISK_GROUP_SCAN_CLIENT: Only the MDR Client shall scan for disks and disk
groups.
•
MDR_DISK_GROUP_SCAN_SERVER: Only the MDR Server shall scan for disks and disk
groups. Currently, only a few features of the disk group are implemented in the
MDR Server. Therefore, only one disk group can be found (with no name).
Returned value:
OK or ERROR.
If
ERROR is returned then the errno variable will be set accordingly. See MdrDefs.h for
MDR errno values.
