[Networker] Disaster Recovery testing
2006-05-09 11:16:35
I will be attempting to do a successful disaster recovery test for the 3rd time
this July. So far, I've yet to come back satisfied with the results. I run 7.2
on a windows 2000 server, and will try to recover 3 linux boxes running AS 2.1
with Oracle overlayed on them. Our Oracle DB won't allow for me to use the
Oracle module that Networker offers, so I backup the whole box and the RMAN
data. Then he gets stuff up and running thru RMAN itself. The RMAN data
consists of about 500 GB. The previous 2 tests were VERY SLUGGISH plus I ran
into reading in the wrong block size on the drives they provided for me. We
have a MSL5000 tape library at home using 160/320 tapes. Does anyone have
specific procedures besides what's in the Administrator's Guide of course that
seems to work for you.
I was given some procedures to follow at the last Sungard test center that
consisted of
1. Install Networker
2.In Networker GUI create a single tape device
3. run inquire to get scsidev address of tape drive or jukebox
4. run sjirdtag x.x.x (where x.x.x is the scsidev address from step 3
5. Run sjimm slot <slot#> drive 1
6. when sjimm has completed run mmrecov
7. the tape drive to be used will be \\.\tape0.
8. enter the ssid and starting file and record numbers when prompted.
9.when the recover completes shutdown the Networker Services
10. in c:\program files\legato\nsr rename the res dir to res.old
11. rename the res.R directory to res
12. remove all of the files from the nst/tmp, but leave the sec subdirectory
13. restart networker
14. reconfigure jukebox and start doing client indexes and then restores can be
done.
It all sounds so easy, except with the last test, legato said that I ran into
every possible problem going. They were blaming alot on networking. We had
everything set to 100/full and I believe the hardware was all up to date.
