Fellow Managers;
I made an error while replacing a disk in a SDS 4.2 raid-1
mirror this morning. Disk 'c1t0d0' was showing intermittent
errors, so I got a new disk and started the replacement process.
I metadetach'd the running sds devices on c1t0d0 from their
running mirrors. I then made my mistake; I deleted the state
db replicas from c1t1d0 and not c1t0d0 as I should have
(metadb -d /dev/dsk/c1t1d0s7).
I did not realize my mistake until after I replaced the bad disk
(c1t0d0) and tried to create the state replicas on it. At the time,
'metadb -i' was showing that the state replicas on c1t0d0s7 were in
'W' state (write errors).
I have backed out of my mistake by placing the original c1t0d0 disk
(the one with intermittent errors) back in the system. I then
re-created the accidentally deleted state db's on c1t1d0s7. Once
created the state db's on c1t1d0s7 looked like this;
a u 16 1034 /dev/dsk/c1t1d0s7
a u 1050 1034 /dev/dsk/c1t1d0s7
a u 2084 1034 /dev/dsk/c1t1d0s7
This didn't look too bad, so I then deleted the state db's on c1t0d0s7
and re-created them. metadb now shows the two sets of state db's as;
a u 16 1034 /dev/dsk/c1t0d0s7
a u 1050 1034 /dev/dsk/c1t0d0s7
a u 2084 1034 /dev/dsk/c1t0d0s7
a u 16 1034 /dev/dsk/c1t1d0s7
a u 1050 1034 /dev/dsk/c1t1d0s7
a u 2084 1034 /dev/dsk/c1t1d0s7
There are however flags missing from the state replicas. An identical
machine I have has the following output from metadb;
a m p luo 16 1034 /dev/dsk/c1t0d0s7
a p luo 1050 1034 /dev/dsk/c1t0d0s7
a p luo 16 1034 /dev/dsk/c1t0d0s7
a p luo 1050 1034 /dev/dsk/c1t1d0s7
a p luo 16 1034 /dev/dsk/c1t1d0s7
a p luo 1050 1034 /dev/dsk/c1t1d0s7
MY QUESTION;
Is there anything wrong with my state db's? ie: Am I screwed if I am
missing the 'm, p, l and o' flags from metadb output?
THANKS! I will summarize.
Chris Price
