MC/Service Guard on 700 Series

[AHMED ABDOU]

I am trying to installed Service Guard for testing purpose, not for HA for product env.

I have one storage ds2100 and two C3600 server with A4999A HBA on both hosts

Questions -

Is MC/Service Guard on 700 Series supported?

I am using normal SCSI Cable not ILT cables as ILT is not supported. How can I change SCSI ID of A4999A card and change on line termination.

Thanks

The answer is this is not supported, and I do not think you can change the SCSI ID of that card.

Hi,
There is ni MC/ServiceGuard for 700 Series AFAIK.

Best regards.

Navid,

It would appear that MC/SG is 800 only: Tier 1 (A through low K), Tier 2 (H through N-class), Tier 3 (T and V-class) - no 700.

Hi everyone,,

Thanks for you quick reply..

Can you please explain, why MC/Service Guard is not supported on 700 series. Because of non multi user env. etc..

As far as A4999A card is concern, I can see two jumpers on card, but I could not find any manual where by I can see their's applicability.

Highly appreciated for your quick responses.

Thanks

It is not supported on 700 series.
You cannot change the scsi id's on these cards as far as I know.
the only way you may be able to check is check this at the BCH prompt before booting the system.

Hello Ahmed,

As Melvyn stated ServiceGuard is not supported, nor is it sold for use on 700 series workstations.

Even if the SCSI addresses were addressable on the 700's SCSI adapters, loading ServiceGuard requires a codeword (= purchase of a license), which codeword is specific to the system in question - it's not transferrable between machines as far as I can tell.

ServiceGuars id not supported on workstations. But it should work for "playing" purposes. That is I would not use it as a testbed for a HA system, but to play wit for getting used to ServiceGuard. I run a one node cluster on a C110. :-)

If you have unlocked ServiceGuard from the applications CD, you *can* install it on a 700. I have tried this on a dual-CPU J system, to amuse myself.

I wasn't able to connect two boxes to a lock disk as I could not change the SCSI controller card address, as others have mentioned.

For testing, I would nab a couple of used D boxes from Ebay... :) Actually, any 800-class system would do nicely...

Hello Everyone,

Thanks for participation,

I know very well, MC/Service Guard is not supported on 700 Series, but I would like to install for test purpose,
FYI, I am able to installed S/W successfully on 700 Series, I would like to change SCSI ID of SCSI Controller (A4999A) for shared bus configuration on two node cluster. I am interested in pure HA Env. Just is just for training.. and for conceptualization.

I would like to know.. How can I change SCSI ID to 6 from 7. If I go BCH, then Main Menu .. Configuration.. I did not find any SCSI option... I can see I/O adapter.. How can change SCSI ID..
If I use SCSI INIT 6 on configuration menu.. Will it work . If yes, then how can I be sure that I am changing additional adapter ID not in built one...

Pls. advise.

Thanks

Hi for changing Instance number use this procedure:
1. ioscan -kf | grep -e INTERFACE -e DEVICE | grep -v target | awk
'{printf "%s %s %s\n",$3,$1,$2}' > infile

2. vi infile ( change instance numbers for interesting hardware path)

3. mv infile /stand/infile

4. mv /stand/ioconfig /stand/ioconfig.sav
mv /etc/ioconfig /etc/ioconfig.sav

5. shutdown -ry 0

6. interrupt the boot process, boot pri, interact with ISL.

7. ISL> hpux -is

8. cd /stand
/sbin/ioinit -c
/sbin/ioinit -f infile

9. reboot

Hello Sabatian,

Thanks for your reply..
Some one has suggested me that you can change via BCH.. If there is no jumber etc on SCSI Card...

Is there any way I can change SCSI ID of that card .. How can I make sure that I am changing additional card SCSI ID not inbuilt SCSI Controller on C3600 Workstation..

I went in Configuration menu of BCH and I did not find any SCSI info. Is it hidden command .. SCSI INIT 6 ,, But how can I make sure it will applied on additional card..

Pls. advise

Thanks

Hi again
unfortunately, changing SCSI id from BCH is only possible on 800, You go to SERvice menu then to SCSI menu. On workstation it is no possible.

Hi,

I do appreciate if you anyone can send me detail which SCSI Card should I use on C3600 so that I can configured ds2100 on shared bus.

I should be able to change SCSI ID as well of the card.

Thanks
