Periodic system dump problem 5

[rightsaidfred]

Hi All,

Could you help please with the following?

I have a BC9 system with 1 lim. Periodic system dump has failed, because of no REL1 and REL2 directories exist any more. Beside this HDU is very-very noisy. It is a 10 year old system.

How can I recreate these REL1 and REL2 directories? Or do you think that HDD gone wrong? If yes, what are the exact steps to change the HDU card with a new one in details?

Thanks in advance!

One thing I'm pretty sure about is if your HDU is noisy then it's almost certainly knackered and needs changing.
What I'm not sure about is how you go about changing the card.
I've changed a standby HDU (BC10) and all that was required was to plug the new HDU in and do a FISBI.
Not sure about a HDU with REL1 and REL2, perhaps someone else can advise?

Thanks DisWire,

Anybody else?

hi
follow the steps to change the HDU:

Block the SCSI port in IPU.
BLEQI:EQU=1-0-00-0;

FIMOE:SUBFS=SYSSUBFS11;
FIMOE:SUBFS=SYSSUBFS21;

FIOFP:NODE=SYSN;

IOSIE:NODE=SYSN,IODEV=SYSDISK1;

( Put the new HDU )

IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11&SYSSUBFS21;

FICRI:SUBFS=SYSSUBFS11,SIZE=60;
FICRI:SUBFS=SYSSUBFS21,SIZE=60;

FIMOI:SUBFS=SYSSUBFS11;
FIMOI:SUBFS=SYSSUBFS21;

BLEQE:EQU=1-0-52-0,ALLFM=YES;

DUSYI;

regards

1 more question.
Do I loose all my config when hdu crashes and there is a power-off and md110 goes off. Or there is a backup somewhere else?

Hi

If you don't have a valide backup on HDU and if you have a power failure at the same time, then you will have trouble as there is no other backup as HDU and memory of the system.
My suggestion is to make a PC Regen and replace your HDU ASAP to avoid problem on customer site.

 

[DisWire]

You may have an additional HDU in the system that is used for safety back ups. You can reload from that but unless regular FISBI's have been done the data held on it my be out of date.
As previously stated don't delay and get the HDU replaced ASAP.

bija77!

Is it doing the formatting and also copying the program units, not only the config? How long will it take?

Thanks!!!

hi rightsaidfred,

the only DUSYI command will take long time.

My suggestion is to make a PC Regen (Exchange data backup in pc)and replace your HDU ASAP,because if you have a power failure you will loss the data.

One more question!
Lets assume that I loose data. I buy immediately the HDU card. How can I rebuild the config? Is it possible to put the hdu into a working md110, do a DUSYI, insert the hdu into the lost md110, delete old settings/config, recreate whole system programming from PC Regen?
If not, what's the way to do?

Thanks!

 

[bija77]

dear,
If you loss the data, you must follow the steps:
1-Go to working MD110 BC9 and take the INL (initial load directory) by sent the following commands:
Block the SCSI port in IPU.
BLEQI:EQU=x-x-xx-0; (x-x-xx the IPU board position)
FIMOE:SUBFS=SYSSUBFS11;
FIMOE:SUBFS=SYSSUBFS21;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;
( Put your new HDU )
IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11;
FICRI:SUBFS=SYSSUBFS11,SIZE=60;
FIMOI:SUBFS=SYSSUBFS11;
BLEQE:EQU=x-x-xx-0,ALLFM=YES;
DUSII;
Dusii command will take long time (note DUSII not DUSYI) Now remove your HDU as following:
Block the SCSI port in IPU.
BLEQI:EQU=x-x-xx-0;
FIMOE:SUBFS=SYSSUBFS11;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;
(Now remove your HDU and Put the original HDU )
IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11&SYSSUBFS21;
FICRI:SUBFS=SYSSUBFS11,SIZE=60;
FICRI:SUBFS=SYSSUBFS21,SIZE=60;
FIMOI:SUBFS=SYSSUBFS11;
FIMOI:SUBFS=SYSSUBFS21;
BLEQE:EQU=1-0-52-0,ALLFM=YES;
IODDP;
DUBDP;
Now you have the INL in your HDU.

2-Install the HDU in your system and turn the MD on (until the LPU display shown number 101).

3-Transfer the suitable LIM disp. Table to the MD.

4-After you finish you can make format to your HDU again (to create subfs21)as following:
Block the SCSI port in IPU.
BLEQI:EQU=x-x-xx-0; (x-x-xx the IPU board position)
FIMOE:SUBFS=SYSSUBFS11;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;
IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11&SYSSUBFS21;
FICRI:SUBFS=SYSSUBFS11,SIZE=60;
FICRI: SUBFS=SYSSUBFS21, SIZE=60;
FIMOI:SUBFS=SYSSUBFS11;
FIMOI:SUBFS=SYSSUBFS21;
BLEQE:EQU=x-x-xx-0,ALLFM=YES;
DUSYI;

5-Now you can transfer the data from the PC-Regen or you can program the exchange manually.

It was very-very helpful!
Thank you very much!

Bijja,

is it the same steps for ATA HDU?

I mean, suppose i want a copy of HDU7 (ROF 137 5398/1 R1D in TS71(A)) data in another HDU 7 (ROF 137 5398/1 R1E in TS72 - not operational)
which steps should i avoid from the above?

thanks for the information

Dear ALL,
Sorry every one there is a small mistake in the above procedure: just when you remove your new HDU and Put the original HDU we don’t need to the two commands FICRI so.

(Now remove your HDU and Put the original HDU)
IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11&SYSSUBFS21;
FIMOI:SUBFS=SYSSUBFS11;
FIMOI:SUBFS=SYSSUBFS21;
BLEQE:EQU=x-x-xx-0,ALLFM=YES;
IODDP;
DUBDP;

regards,

Dear Monrovia,

If you need to copy the data from the HDU7 to another one you must follow the steps:
1- Block the SCSI port in IPU.
BLEQI:EQU=x-x-xx-0; (x-x-xx the IPU or NIU board position)
FIMOE:SUBFS=SYSSUBFS11;
FIMOE:SUBFS=SYSSUBFS21;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;
( Put your new HDU )
IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11&SYSSUBFS21;
FICRI:SUBFS=SYSSUBFS11,SIZE=60;
FICRI:SUBFS=SYSSUBFS21,SIZE=60;
FIMOI: SUBFS=SYSSUBFS11;
FIMOI: SUBFS=SYSSUBFS21;
BLEQE:EQU=x-x-xx-0,ALLFM=YES;
DUSYI;
DUSYI;
DUBDP; (to make sure that the REL1 and REL2 is ok)
Now you have a backup HDU with the Exchange data
To return the original HDU
2- Block the SCSI port in IPU.
BLEQI:EQU=x-x-xx-0; (x-x-xx the IPU or NIU board position)
FIMOE:SUBFS=SYSSUBFS11;
FIMOE:SUBFS=SYSSUBFS21;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;
( remove the new HDU and Put the original HDU )
IOSII:NODE=SYSN,SIPOS=3,IODEV=SYSDISK1,SUBFS=SYSSUBFS11&SYSSUBFS21;
FIMOI: SUBFS=SYSSUBFS11;
FIMOI: SUBFS=SYSSUBFS21;
BLEQE:EQU=x-x-xx-0,ALLFM=YES;
DUBDP;

Hi Morovia

ATA bus behave differently from SCSI buses.
First, the NIU2 support only 2 drives; either a flash card and a HDU7 or 2 HDU7
Second if you want to add a extra HDU on the ATA bus already existing, you have to set it as salve HDU and reboot the NIU in order for the ATA bus to detect the new disk. Setting slave or master on HDU depend on place you put the Cable between NIU2 and HDU: lowest position is master.
If there is a flash card, the flash card is always master.

When initiating the disk, with the commande IOSII, you have to specify a new parameter BTYPE that indicate if it is ATA or SCSI.

Then you can do a copy with the command FICPI.

My suggestion is to adda second NIU2, if possible and dedicate it for the copy. In this condition you will avoid to reboot the 'executing' NIU each time you add or remove the HDU

Best regards

Thanks a lot Bijja for the nice studyclass

Fausnant, actually i dont want to use to HDU7 in the system. so the steps by bijja will do for me.
Thanks for the Explanations.

But your suggestion is too good for anyone who is trying to use two HDU s in a system. I will remember it for my future.


One suggestion to the Moderator of this forum:

Can you keep this thread in FAQ. it will be useful for those who are searching for replacing the HDU, copying the HDU.
