Problem-Isolation and Debug Commands

Problem-Isolation and Debug Commands

The IPSSEND problem-isolation and debug commands include the following:

CERTIFY Use the CERTIFY command to verify the media of a hard disk drive.
If the program finds a media error, it reassigns the sectors.
A summary of reassignments and PFA errors appears upon completion of the verification.
Supported operating system: DOS

Command:  IPSSEND CERTIFY Controller Channel SID

Replace: 

•  Controller with the ServeRAID controller number (1 to 8)
•  Channel with the channel number for the device (1, 2, or 3)
•  SID with the SCSI ID for the device (0 to 15)

ERASEEVENT Use the ERASEEVENT command to clear all logged entries in the designated event log.
See GETEVENT help for information about the contents of the Device Event Log and the Adapter Soft and Hard Event Logs.
Supported operating systems: Windows NT, O/S2, Netware, OpenServer, UnixWare, and DOS

Command:  IPSSEND ERASEEVENT Controller Options

Replace: 

•  Controller with the ServeRAID controller number (1 to 8)
•  Options with one of the following:
  •  DEVICE for the Device Event Log
  •  SOFT for the ServeRAID adapter or controller Soft Event Log
  •  HARD for the ServeRAID adapter or controller Hard Event Log

FMSTATUS Use the FMSTATUS command to display the progress of a format operation currently processing.
Supported operating system: DOS

Command:  IPSSEND FMSTATUS Controller Channel SID

Replace: 

•  Controller with the ServeRAID controller number (1 to 8)
•  Channel with the channel number for the device (1, 2, or 3)
•  SID with the SCSI ID for the device (0 to 15)

FORMAT Use the FORMAT command to perform a low-level format of a hard disk drive.

  -Attention- When you issue this command, all data on the drive will be lost.
Supported operating system: DOS

Command:  IPSSEND FORMAT Controller Channel SID

Replace: 

•  Controller with the ServeRAID controller number (1 to 8)
•  Channel with the channel number for the device (1, 2, or 3)
•  SID with the SCSI ID for the device (0 to 15)

GETEVENT Use the GETEVENT command to display information about various unexpected events.
IBM uses the Soft and Hard Event Logs for development and debugging purposes only.
The Device Event Log contains event counters for each attached physical device.
These counters include:

•  Parity: An unexpected event while transferring data on the SCSI bus.
   This usually indicates a problem with the SCSI cable, connectors, or terminators.
•  Soft: A SCSI device detected a check condition event.
•  Hard: The SCSI controller detected an unexpected event.  The controller is the most likely cause.
•  Misc: The ServeRAID adapter or controller detected an event that was most likely caused by the device.

•  Controller with the ServeRAID controller number (1 to 8)
•  Options with one of the following: DEVICE for Device Event Log, SOFT for the ServeRAID adapter or controller Soft Event Log,  or HARD for the ServeRAID adapter or controller Hard Event Log.

SELFTEST The SELFTEST command is used to direct an adapter or a device to perform its self-test.
Supported operating systems: DOS

Command:  IPSSEND SELFTEST Controller Options

Replace: 

•  Controller with the ServeRAID controller number (1 to 8)
•  Options with AD for the ServeRAID adapter or controller self-test or PD Channel SID for the Device self-test.

  Note: Channel represents the drive channel and SID represents the SCSI ID for the device.

STARTDELY Use the STARTDELY command to set the number of drives in a group to start up simultaneously and to set the delay in seconds between the startup of these groups of drives.
Supported operating systems: DOS

Command:  IPSSEND STARTDELY Controller Options

Replace: 

•  Controller with the ServeRAID controller number (1 to 8)
•  Options with a question mark (?) to display concurrent drive startup count: Drive Count (1 to 16) and Delay Time (3 to 15 seconds).
