just upgraded to 7.65 got questions

[anlgdog]

Was running 3.0 before now. My midnight routine would do LDs 30, 43, 45, 60, 135 and backup to a floppy and then switch CPU nightly. This way my two CPU's were put to use every other day plus both floppy's held current info. Now with 7.65 it still does all my midnight routine LDs and does a backup to a new compact flash or Removable Media Device [RMD] but it does not switch CPU's anymore. I have been on CPU 1 ever since upgrade. I'm thinking my RMD on CPU 0 has not been backed up ever and not sure if CPU 0 is worthy of a switch if needed. I did a LD135 SCPU to get it over on CPU 0 thinking to run it there for a few days but shortly after I left the site location it did a switch back to CPU 1. I'm confused on this.
Like to hear from others and how they are running as well.

Yeah, I heard the same thing (that you don't need to swap CPUs anymore ... I am trying to recall the reason ... I think everyone likes to at least test by switching it every so often ... It is a bit strange to get used to

The Nortel (real Nortel Eng.) had told us to not have the cpu's swap every night. But if you make changes, move the media devices when doing the edd's and just make it a habit. That way you backup is always current.

If its not working, get a bigger hammer!

I wondered about the no-swap thing too at first. I can't remember which release it was introduced but Nortel later gave us the option of allowing the swap.
LD 17
OVLY gateopener
MID_SCPU (NO) YES

But I'm happy to leave it at the default (no swap) for two reasons.
1. There is a short (few seconds) interruption of new call processing.
2. Why tempt fate? Yes, the inactive cpu is being monitored for health status, but if something does go wrong on the swap, I would rather be in the room when it happens than get a call at 2:00am.

There's a pretty good rundown of the options in NN43001-507 System Redundancy Fundamentals in the section Campus Redundancy, Normal Operations, Switchover.

If you swap CPU's in the later releases after it swaps it does an INI on the active side. Not a good thing when you have 24 hour operation. Also the side it just swapped from does a sysload. I would highly recommend you do not have them swap.

Thanks for the replies. I'll go with the "No Swap" idea on my CPU's. I'm constantly doing phone moves or changes allot here, guess I'll get into the habit of swapping my RMD maybe once a week and take my 3rd RMD over to the tape vault for safe keeping.
Also I have noticed another pattern that once a week it does an additional backup 1hr before my midnight routine. I see the message: TEMU193 Scheduled Backup according to rule (1) ended successfully. My System Messages book is for older version and doesn't have this TEMU message listed.

 

[KCFLHRC]

Someone has configured a backup rule for Geographic Redundancy .That is the message you are seeing. Do you have an alternate call server?

 

[KCFLHRC]

TEMU0193 "<mode> Backup according to rule <n> ended successfully."
Where n - the number of the backup rule that was used, and mode of the
Backup may be "Automatic", "GR Manual" or "Manual"
Action:
Severity: Info. Critical to Monitor: No. SNMP trap: Yes

 

[anlgdog]

At the start of the backup reads:
Starting Backup according to Rule 1
Backup mode: Scheduled
Backup Rule type: PFMD
Starting database backup to "/e/bkbd/backup/tmp"

This is different from my midnight routine that says: Backing up reten.bkp to "/cf2/backup/single" and then mentions process to local RMD ended successfully.

I'm wondering could this be backing up to my RMD located in the standby CPU 0 ? Since it only happens once a week.

 

[KCFLHRC]

You can print the back up rules in LD 117,

Req = prt
type = bkpr

return
return

 

[anlgdog]

Ok, never been to LD 117, didn't get Req = instead I got => then I typed "P BKPR" return and it printed: 1 PFMD 1 RuleByDefault
Now I need the definition of PFMD.

 

[KCFLHRC]

Not sure what PFMD is, obviously FMD is Fixed Media Device, not sure what the P is though. Sorry bout the REQ thing, what you saw is correct.

Hi,

PFMD is on the protected part of the FMD, and is automatically generated when upgrading to Rls 7.6 as part of the quality strengthening of the CS. It's not only used for geographic redundancy, you can use it to send the backup to a remote FTP server on a weekly basis so you can have 10 weeks of backup on a remote location, or on the RMD device of the CS. You can also make it a monthly backup if you want.

Nevertheless, the CS will still run the EDD to both FMD and RMD, in the midnigh routine and this will not overwrite the backups from bkpr in ld117.
