G.1.2 Conditions of Usage


G.1.2 Conditions of Usage
The following conditions apply when using the XSCF startup mode function.
  1. If the startup mode is set to "fast" mode with the xscfstartupmode command, and the input power is turned on with the operation panel mode switch set to "Locked", the system will be started in the "fast" mode. However, even if the startup mode is changed to "fast", if the operation panel mode switch is changed from "Service" to "Locked" after the input power has been turned on, the system will be started in "normal" mode, not "fast" mode.
  2. When the startup mode is changed to "fast," a reboot of the XSCF does not cause the physical partition to start automatically. Automatic activation of the physical partition operates only when the input power is turned on.
  3. The startup mode of the system cannot be changed only by executing the rebootxscf command after changing the configuration of the startup mode. Turning off/on the input power is necessary to make the changed startup mode setting effective.
  4. The configuration of the startup mode is saved in the XSCF on the motherboard unit (MBU), but internal backup to the PSU backplane unit (PSUBP) is not performed. If the MBU is replaced, the startup mode may change to the default setting. After MBU replacement, make sure to check the startup mode and, if necessary, change the startup mode to the desired setting.
  5. When the system is started in the "fast" mode, do not change the configuration of XSCF or perform degradation/restoration, or configure the environment parameters of the OpenBoot PROM, or save the configuration information of logical domains. Perform these operations only in the "normal" mode. If you perform the above operations when the system had been started in the "fast" mode, the configurations and changes will be saved to the XSCF on the MBU, but internal backup to the PSUBP is not performed. If the MBU is replaced, the configuration information will not be recovered from the PSUBP internal backup, and the system may not be able to start.
In addition to the XSCF startup mode function "fast" setting, the time taken from applying input power to the system to the start of Oracle Solaris/Oracle VM Server for SPARC can be further reduced by:
  1. Using Solid State drive (SSD) internal storage as boot devices (rather than SAS disks)
  2. Setting the POST diagnosis level to off (from the default of min)
Note - When changing the POST diagnosis level, be sure to change the setting after confirming the contents of "G.2.2 Restrictions and Notes at the Time of System Operation."
