Support is included for the Integrated 32-Bit Fast-SCSI-2 Controller in Compaq ProSignia and Compaq ProLiant servers. Support is also included for the Compaq 32-Bit Fast-SCSI-2 Controller Option Board which may be installed in any Compaq EISA system.
%adapter addr1-addr2 irq - type=cha ha=ha id=id class slot=slot geo=g wid=w Compaq Fast-SCSI-2 (rev 1.9.0)This message indicates that the Compaq 32-Bit Fast-SCSI-2 Controller driver has successfully initialized a controller. The controller initialized is using I/O addresses addr1 through addr2, handling interrupts using IRQ irq, and will not use DMA. The host adapter type is cha, the host adapter number is ha, the host adapter is using SCSI ID id. The controller class is EISA or PCI, the slot number is s, the default hard drive geometry algorithm for drives connected to this controller is g, and the width of the SCSI bus on the controller is w bits. This message may be used to determine the physical location given the host adapter number.
cha: The SCSI adapter driver detected an unrecoverable error Correct earlier errors and rebootOne of the previous warning messages from the cha driver will indicate a condition which would prevent successful system boot. The system is stopped to prevent subsequent secondary error messages from causing messages about the primary problem to quickly scroll off the console screen.
cha: Unable to allocate memory (x bytes) One or more configured SCSI host adapters will be unavailable The system needs more memory available to boot this kernel (chaW01)x is the requested amount of memory in bytes. This message indicates that a request for memory at initialization time has been refused by the kernel. The kernel you are booting is too large to run correctly with the amount of memory detected by the kernel. Be sure your system has sufficient RAM memory and that this memory is configured so that the UNIX kernel can detect it.
cha: The SCSI controller for the root drive must be host adapter ha=0 Use Compaq System Configuration Utility Change the SCSI Controller from ha=ha to ha=0 slot=slot (chaW09)The host adapter in this slot was selected during System Configuration to be the hard disk boot controller, but it was not also set to host adapter number 0. UNIX expects the SCSI boot device to be attached to host adapter number 0.
cha: Compaq SCSI Adapter Failed slot=slot Use Compaq Diagnostics to confirm a hardware failure (chaW11)The driver has detected failure of the SCSI controller in this slot. Follow standard procedures to locate and repair the failed component.
cha: Compaq SCSI Adapter detected cabling error slot=slot Check for proper attachment and termination of SCSI cables (chaW12)A cabling error has caused the driver to detect a SCSI bus termination error. Communication between this host adapter and SCSI peripherals is not permitted.
cha: Host adapter number ha=ha conflict detected slot=slot This controller will not be enabled Use Compaq System Configuration Utility to set host adapter number (chaW15)The host adapter number for this controller is set to the same value as the host adapter number for another controller in this system. UNIX uses this number to uniquely identify a single controller to the driver. The host adapter number for one of these controllers must be changed so that both may be used. Both controllers are currently set to host adapter ha. The controllers is in this slot has been disabled due to the conflict.
Although these conditions are abnormal, the driver continues to function normally. The commands may have been retried and completed successfully. If the same message appears multiple times, this may be due to the same command being retried several times with the same result.
If the command was not retried successfully, another driver may subsequently report a related error. All of these conditions are unexpected. Although they may be recoverable, you should attempt to determine their root cause and correct it.
cha: SCSI data overrun ha=ha id=id lun=lun cmd=cmd blk=blk len=len Data arriving from a SCSI peripheral over-filled storage (chaN00)A peripheral on the SCSI bus has attempted to send the host more data than was requested.
cha: Unexpected SCSI disconnect ha=ha id=id lun=lun cmd=cmd blk=blk len=len A SCSI peripheral unexpectedly stopped communicating with the host (chaN01)A peripheral on the SCSI bus has disconnected unexpectedly.
cha: Unexpected SCSI phase ha=ha id=id lun=lun cmd=cmd blk=blk len=len A SCSI peripheral behaved unexpectedly Use Compaq Diagnostics to confirm a hardware failure (chaN02)A peripheral on the SCSI bus has made an unexpected phase transition.
cha: SCSI device has been reset ha=ha id=id lun=lun A SCSI peripheral driver requested this action (chaN03)A reset command has been sent to a peripheral on the SCSI bus. This host initiated action is usually a response to some other abnormal condition.
cha: SCSI bus has been reset ha=ha Attached SCSI peripherals will return to power up state (chaN04)A reset has been sent to the SCSI bus. This host initiated action is usually a response to some other abnormal condition. Each peripheral on the SCSI bus will perform power-on initialization in response to bus reset. SCSI tape devices will immediately rewind.
cha: SCSI command timed out ha=ha id=id lun=lun cmd=cmd blk=blk len=len A SCSI peripheral failed to report completion status in time (chaN05)A peripheral on the SCSI bus accepted a command from the host but the host did not receive completion status from the peripheral within the maximum time permitted for this command on this class of peripheral.
cha: SCSI bus parity error ha=ha id=id lun=lun cmd=cmd blk=blk len=len The host detected a single bit error on the SCSI bus (chaN06)A parity error was detected by the host during a transfer over the SCSI bus.
cha: SCSI data underrun ha=ha id=id lun=lun cmd=cmd blk=blk len=len Data arriving from a SCSI peripheral under-filled storage (chaN07)A peripheral on the SCSI bus sent the host less data than was requested.
cha: No host adapter number ha=0 found Check your configuration (chaN09)This may be a configuration error. A SCSI controller may have been disabled or removed. UNIX configures host adapters consecutively starting with 0.
cha: Some host adapter numbers between ha=ha and ha=ha2 were not found Check your configuration (chaN10)This may be a configuration error. A SCSI controller may have been disabled or removed. UNIX configures host adapters consecutively. The lowest host adapter number detected and enabled by the driver is ha, the highest is ha2.
