All...
Here is the situation. We have an 8400 as an oracle database server. DUNIX
V4.0d. This contains a number of ESA10000 cabs with 9 and 18gb disks (a cab
has only 18's or 9's, not both).
We are replacing the 9's with 18's. The DBA moves the data from an entire
cabinet, I then do the following:
a. Delete all the lsm volumes (this is raw storage, not file systems)
d. Once there are no subdisks remaining, delete the disk(s) from its disk
group
c. Do the business on the HSZ (the detail from this point onwards is not
important.
Once the new 18's come online, they are going into A DIFFERENT disk group
from where the 9's came from.
The problem is as follows. The disk group in question had 16 disks (HSZ
based stripe sets) - that's disks not volumes.
I have happily removed 7 (of 8) disks using "voldg -g ??? rmdisk rz????".
When attempting to remove the 8th disk (there are, at this point still 9
disks within the disk group), I get a failure to the effect that "cant
remove last disk group configuration copy".
I have checked ALL the 9 disks within the group for the existence (or not)
of configuration copies. The disk in question does indeed seem to have the
last configuration copy:
#voldisk list rze144 | grep -i configs
configs: count=1 len=726
#voldisk list rzc104 | grep -i configs
configs: count=0 len=0
#voldisk list rzc112 | grep -i configs
configs: count=0 len=0
#voldisk list rzd104 | grep -i configs
configs: count=0 len=0
#voldisk list rzd112 | grep -i configs
configs: count=0 len=0
#voldisk list rze104 | grep -i configs
configs: count=0 len=0
#voldisk list rze112 | grep -i configs
configs: count=0 len=0
#voldisk list rzf104 | grep -i configs
configs: count=0 len=0
#voldisk list rzf112 | grep -i configs
configs: count=0 len=0
The new 18's are going into a different disk group.
Question - Can I add a configuration copy to an EXISTING disk with EXISTING
data on it? If so how. I've checked the archives for 98/99 and cant see
any similar problems. The LSM reference manual doesn't mention it either.
Any suggestions would be appreciated.
Thanks - Tony
