ISM Errata: Important Information about ISM 5.5.5 For Your HP cc3310 Carrier Grade Server

4
PROBLEM: Due to the rounding of floating point values, the user can set different threshold values without any
effective difference between them. This is possible only if the user tries to set different threshold values so close to
each other that the hardware characteristics of the sensors are bypassed.
IMPLICATION: The user may be able to set the same value for different sensor thresholds.
WORKAROUND: Do not set different threshold values very close to each other.
8. Actions for some hot-swappable power supply events may not be set and handled properly.
PROBLEM: ISM PIC supports control actions for events such as “Power supply failed”, “Power Supply OK,” and
“Power Supply Likely to fail.” These events include situations of the power supply failing or the internal power cable
coming loose, but they do not cover events such as removal and replacement of the hot-swap power supply, or
removal of the AC input power cord.
Furthermore, after the removal or insertion of a power supply unit, ISM PI may not handle any of the power supply-
related events properly. This means that if you set a control action to occur on power supply failure, then replace a
power supply without rebooting the OS, if a power supply subsequently fails, the control action may not occur.
IMPLICATION: The system may not perform the requested control actions set for the power supply sensors.
WORKAROUND: None.
9. Auto-refresh of health status on the ISM PIC GUI may not work when monitoring a Windows-based server.
PROBLEM: Auto-refresh in ISM PIC may not work when monitoring a Windows-based server across subnets.
IMPLICATION: The PIC console may not accurately reflect the current health status of sensors for Windows-based
servers, if the server and client system are in different subnets.
WORKAROUND: There are two options if this failure occurs:
a. Map a drive to the server being monitored. Then set broadcast alert messages for any sensors you wish to monitor.
b. Use F5 to refresh the ISM PIC GUI; this updates the current health status of the sensors and ISM.
ISM Console
If you plan to use any ISM Fault actions to power the system down you should pre-configure Linux to automount USB
Floppy. In cases where the event that caused the system to power down has not been fixed or cleared, the system will
automatically power down upon reaching the OS. To allow you to recover from this, the system will look for an
lra.not file on the fd0: drive. For details see “Avoiding a Power On/Off Loop” under ““Cautions in Setting
Thresholds” in the ISM Install and Users Guide.
Control actions such as: Cannot be set for these events:
• Shutdown the OS
• Shutdown the OS and
Power off, and so on
• “Power Supply Inserted”
• “Power Supply Removed”
• “Power Supply AC lost”
• “Power Supply AC lost or out-of-range”
• “Power Supply AC out-of-range, but present”
WARNING The ISM Console works by receiving alerts from the managed systems. It will not detect
when the server loses its network connection with the management station. It will also not
report drive failures. This is “by design.”
