Hello all

Whilst not strictly AIX, I'm sure people here have been asked the same
questions.

It's upgrade time again, and I'm looking at de-comissioning a couple of
S80's in a 2 node HACMP cluster. I still need HA, but am looking at
possibly implementing a pair of Linux (RedHat) Intel boxes.

Is there any good HA software people have used for Linux? I'v been
reading a little and have some concerns. For one, the cluster software
you can get from RedHat doesn't seem to implement any SCSI reservation
locking...

We have enjoyed very good uptime from the S80's and I'd like the trend
to continue

Your thoughts would be appreciated.

Thanks

Steven

Have a look at linux-ha.org. re SCSI locks I believe Redhat is pushing
GFS and clustered filesystems so you wouldn't want SCSI locks in those
cases... Or for Oracle you could use RAC, or DB/2 (parallel edition?)

GAaacckkkk - I hear tell there's a product called "HACS" out there
somewhere (google search?). It's supposed to be the Linux (ES versions,
that is) equivalent of HACMP for AIX.

HTHS(what <G>).

Hi Steven

as noted linux-ha.org (this product is written by a chap called simon
edwards who i used to work with) also, you have service guard for linux
which is similar to the hpux product.

when you mean scsi reservation locking, do you mean a lock disk for
quorum ?
