How to setup Solaris to provide SRDF bootdisk cluster-like functionnality ?
Hello,
We have 2 identical solaris machines (A & B) and 2 Symmetrix on 2 sites. We would like to move from internal scsi boot disk to SRDF symmetrix bootdisks. This way we can be able to backup server A on the B hardware or the opposite according our needs.
We also have PowerPath. I would like to know if we have to use persistent binding four our symmetrix boot devices (until now we don't) to make sure the emcpower devices will always be the same even if we have minor differents thirds luns on the SAN.
I suspect a boot -r in a case of a different naming of Solaris could fail the boot processing.
Any experience about that configuration will be appreciated.
Regards
Dak

I imagine you will want to enable persistent binding to avoid hardware path changes making it impossible/difficult to boot off of once you convert to SAN bootdisks.
Thanks,

We don't use persistent binding because all SAN disks belongs to Veritas Volume Manager and until now it would have been a non necessary constrainst.
At a first glance, I suppose making persistent binding on the boot lun is necessary. But i'm not sur of the behaviour of the R1/R2 rollover behaviour (i guess the powercf -Z exists for that).
The main concern is to be sure the link emcp device -> (CxTydZ)s -> R1/R2 when the backup will go on.
I was hoping a blueprint could exist about this subject.
