SGLX11.19 not certified on RHEL4

David M Ford — Tue, 12 May 2009 14:43:51 GMT

RHEL4 is not listed on the Certification Matrix for SGLX11.19. Does this SG require RHEL5, or is it just that it is not certified to behave on RHEL4?

Shalom,

Could mean a few things.

1) HP is not done certifying the software on RHEL 4.
2) HP has no plans to certify the software on RHEL 5.

It is doubtful but not impossible that SGLX 11.19 will work on RHEL 4 if not certified.

RHEL4 is very close to its end of support (see the Red Hat site). Because of that it does not make sense to support RH4 with SGLX 11.19. The documentation is correct - SGLX is supported only with RHEL5 and SLES10.

It will not work with RHEL4. Some SW designed for a specific distro will work with others. That is not true with middleware like SGLX that has tighter ties to the OS.

Are they not the same thing really? Would you really consider running it on an unsupported OS even if you happened to find it did work?

SG 11.19 is unsupported on RHEL4. That should be enough. It therefore requires RHEL5 or SLES10.

Hi,
Another thing to add, perhaps if RHEL4 is not supported also it's because SG like redhat cluster suite work with persistent reservations? Do you confirm ServiceGuard for Linux?

And you shoud have to use the sg3_utils package with the sg_persist command which for rhel4 is very old and have some bugs.

Finaly, if you want to use SGLX11.19, install it on RHEL5.0.

Thanks for the help.

Because of specialized applications, customer is currently frozen at RHEL4. Failover time is an issue, so the improvements of 11.19 are attractive, at least. Looks like our best option right now is to give 11.18 a try and hopefully the failover will be fast enough.

Being armed with info re product plans and decision reasons is what I was looking for.
