They appear not to be in RHEL5.3. The only mention of rdac I see in the 
changelog of 2.6.18-128.4.1.el5 is this one:

* Fri Sep 12 2008 Don Zickus <dzickus at redhat.com> [2.6.18-112.el5]
...
- [scsi] scsi_dh: add rdac handler (mchristi at redhat.com ) [438761]
...

I did look at the RHEL 5.4 beta, and there are other updates mentioned in 
changelog there:

* Wed May 20 2009 Don Zickus <dzickus at redhat.com> [2.6.18-150.el5]
...
- [scsi] Retry mode select in rdac device handler (Jesse Larrew ) [489582]
...
* Fri May 01 2009 Don Zickus <dzickus at redhat.com> [2.6.18-143.el5]
...
- [scsi] add md3000 and md3000i entries to rdac_dev_list (John Feeney ) 
[487293]
...

Jacov, you might want to look at the above bugzilla. There is some 
discussion of failover behaviour which might be useful to you.

Yes I would. Or better, if you see any required patches which are not 
included in RHEL5.4, please let RedHat know (via Bugzilla). I will ask 
them to add support for the StorageTek 2510 and 2530 arrays.
