I'm working with Compaq on a problem with one of my 4.0F clusters. It seems
that my DRD services won't start on one member after altering the SAN
configuration.
The DRD devices are used by Oracle and have non-standard disk labels, such
that the b, c, d, e, f, g, and h partitions are in use. These partitions are
all defined in the disk label to be non-overlapping:
8 partitions:
# size offset fstype [fsize bsize cpg] # NOTE:
values not exact
a: 131072 0 unused 0 0 # (Cyl. 0
- 25*)
b: 409600 131072 unused 0 0 # (Cyl.
25*- 106*)
c: 358400 540672 unused 0 0 # (Cyl.
106*- 176*)
d: 358400 899072 unused 0 0 # (Cyl.
176*- 247*)
e: 4718592 1257472 unused 0 0 # (Cyl.
247*- 1176*)
f: 11534336 5976064 unused 0 0 # (Cyl.
1176*- 3446*)
g: 11534336 17510400 unused 0 0 # (Cyl.
3446*- 5717*)
h: 6511653 29044736 unused 0 0 # (Cyl.
5717*- 6999*)
The Compaq engineer I'm working with has latched onto this as the major
problem, saying that this sort of thing is not supported and will cause
unpredictable operation and must be fixed. For the purposes of
troubleshooting, I just said "OK", and added another disk with a standard
label and reproduced the problem with that disk.
In the meantime, does this not being able to modify disk labels sound
correct to y'all's collective wisdom? Even the installation procedure gives
you the option of altering the disklabel to set the size of the root and
swap partitions. Or did they go too far when they configured this particular
disk?

longer than you expect, even if you take this into account. - K. Ingham
