•After switching on IOP, no message
displayed on console terminal
Verify power supply section, EPROM on controller cards, cabling on
to console terminal or terminal
•Boot block corruption messages
Format the hard disk and load full software deliverables
•While loading on IOP, "no disk space"
message comes onto terminal
Format the hard disk and load software once again
•Getting display of "un-correctable
error" on console terminal
Hard disk may be faulty. Format the disk and try again
•While booting IOP, error message displays
on terminal
Proper shut down and booting procedure to be followed
•While loading the software, error comes
as ‘get help’ perhaps ‘c’ option to be used.
Cartridge or cartridge drive may be faulty
•CRP fail to be run with error "IPCRM
ERROR CASE RMIF“
Execute the command in iop prompt;
IOP5x> ipcrm -Q805
•Sometimes on IOP prompt control D not
found message displayed after giving control D
Copy CRP files from base cartridge
•Not accepting any command on console
port
In the operator terminal, find the pid number for console and kill
the process.
iop5X> ps -ef | grep console
note down the PID value (XXXX)
IOP5x>kill -9 xxxx
‘ Now console login will appear in the console terminal’
•By mistake at the time of software loading
same IOP ID given on both the IOP
First identify which is IOP-0 and IOP-1, then give SET IOPID command
in /code/audit directory, and then shut down and boot the IOP.
•Sometimes used cartridges cannot be able
to overwrite in the used catridges
Use expiry over option and use the cartridge.
•Displ-tape-info, copy-out, copy-in command
executed but says tape is not in proper format
Cartridge or cartridge drive may be faulty
•Messages scroll continuously on console
like "message free pool"
Shut down, reboot the IOP or format the hard disk and load the software
•Frequent messages display on terminal
like "medium error on drive
Cartridge drive may be faulty.
•In ‘/u’ directory the free
blocks becomes ‘0’ sometimes
Shut down and reboot the IOP.
•Some times on console terminal few lines
will be displayed like "trans-etnl-seg"
Transaction files may not be matching on both the IOPs. Nullify the
‘iotmsg’ and ‘iotind’ files in both IOPS after
taking ‘trnsf’ back up.
•Getting warning message for disc space
falling below threshold
If the free space goes below 5% of the allotted value this warning
message is displayed. Remove unwanted files and increase the disk
space. (Create space utility can be executed)
•Whenever inter change command is executed
on ‘IOP’ or ‘AP’ in case of MBM / ‘BP’
in case of SBM, IOP goes out of sync.
It could be due to fault in either IOP controller card or AP controller
card in AM or BP controller card in case of SBM or wrong cabling between
IOP and AP/BP
• At times IOP status goes to DISPL-UPDATE-ALL
level
Verify the status by giving displ-iop-level command and check AP communication
is through if not bring into warm start level shut down and boot the
IOP and sync.
