Hello Administrators,
There is a hardware problem with the Boot Disk (disk0, i.e.
/dev/dsk/c0t0d0s2). The disk is replaced. metadb commands are executed
to re-define the database. After re-establishing the mirroring (metastat
shows everything ok), metadb -i shows:
flags first blk block count
a u 16 1034 /dev/dsk/c0t0d0s3
a u 1050 1034 /dev/dsk/c0t0d0s3
a u 2084 1034 /dev/dsk/c0t0d0s3
a p luo 16 1034 /dev/dsk/c0t1d0s3
a p luo 1050 1034 /dev/dsk/c0t1d0s3
a p luo 2084 1034 /dev/dsk/c0t1d0s3
o - replica active prior to last mddb configuration change
u - replica is up to date
l - locator for this replica was read successfully
c - replica's location was in /etc/lvm/mddb.cf
p - replica's location was patched in kernel
m - replica is master, this is replica selected as input
W - replica has device write errors
a - replica is active, commits are occurring to this replica
M - replica had problem with master blocks
D - replica had problem with data blocks
F - replica had format problems
S - replica is too small to hold current data base
R - replica had device read errors
Before the hardware problem, it was like :
flags first blk block count
a m p luo 16 1034 /dev/dsk/c0t0d0s3
a p luo 1050 1034 /dev/dsk/c0t0d0s3
a p luo 2084 1034 /dev/dsk/c0t0d0s3
a p luo 16 1034 /dev/dsk/c0t1d0s3
a p luo 1050 1034 /dev/dsk/c0t1d0s3
a p luo 2084 1034 /dev/dsk/c0t1d0s3
As 'l' and 'm' are missing on /dev/dsk/c0t0d0s2, will a reboot cause
failure ?
Much appreciated your valuable input.
