Unfortunately, I still did not find a solution to my problem... makes me
wonder if Sun did not made this this way to force people to use their
clustering software!
Summary of the problem:
- Two identical servers, E4500, two identical disk shelves, A5000.
- Both shelves connected to both servers.
ls -lL /dev/rdsk/c[012]* on the two machines shows the files as having
the same names, same major number but different minor numbers.
- Even when both systems are booted off a CDROM.
- We tried recabling in each possible way we could imagine... the
numbers change, but never agree.
Thanks for those who replied, especially : george goffe
<grgoffe@yahoo.com>, who suggested and offered ideas on cloning the
system disk.
After I cloned /, /usr, /var /opt of system A, into a disk on system B,
booted system B with -s argument only, no -r, the new system still
changed the minor numbers of my disks on it own accord!!! and the
resulting numbers do not match the original ones.
- ALargent@concordefs.com:
suggested I created those special files my self, and assigning the
"right" minor numbers, using mknod.
Sounds great, but have no clue how to do that.. any ideas?
- mclausen@csit.fsu.edu: suggested:
there are a few files that need to be identical on both machines in
order for this to work:
/etc/path_to_inst
/etc/minor_perm
/etc/name_to_major
I tried copying these files from system A to system B, then rebuilding
the dev tree with devfsadm -C.... no avail.
-MGurugunti@us.nomura.com: If it is for cluster stuff then use hamajor
or haminor commands.
No, we are not using HA software... only bundled Solaris.
Any input highly appreciated.. this is driving me nuts.
Mohamed~
