getevent selftest Attention: 1. When you issue this function, all data on the disk will be lost. 2. After a format function is issued, do not stop it. If a format process is stopped for any reason, the hard disk that was being formatted will not respond to any functions except the format function. Thus, the ServeRAID controller will not be able to recognize functions anymore. To recover the drive, refer to "Recovering from an incomplete format of a physical drive" on page 185. Supported operating system: DOS Command: ipssend format controller channel sid where: • controller is the ServeRAID controller number (1-12) • channel is the channel number for the device (1, 2, 3, or 4) • sid is the SCSI ID for the device (0-15) Use the getevent function 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 occurred while data was being transferred 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 controller detected an event that was most likely caused by the device. The device event log also provides Predictive Failure Analysis (PFA) alerts, which indicate that the device has signaled the ServeRAID controller that it might fail in the near future. Supported operating systems: Windows NT, Windows 2000, OS/2, NetWare, Linux, OpenServer, UnixWare, and DOS Command: ipssend getevent controller options where: • controller is the ServeRAID controller number (1-12) • options is the designated event log: - DEVICE for the device event log - SOFT for the ServeRAID controller soft event log - HARD for the ServeRAID controller hard event log The selftest function is used to direct a controller or a device to perform its self-test. Supported operating systems: DOS Command: ipssend selftest controller options where: • controller is the ServeRAID controller number (1-12) • options is the designated self-test: - AD for the ServeRAID controller self-test - PD channel sid for the device self-test Installing and configuring ServeRAID controllers 171
