SUMMARY: (re)boot -r on Solaris 8 with Ibm SVC reshuffles vpaths

Thanks to Vikash, who hits the button.
The solution was to use persistent binding in the Qlogic config.

Thanks.

vpaths


	Hi,

	Hope someone can help me.
	We have a Fujitsu Primepower 850, with Solaris 8 and Solaris
Volume Manager and Qlogic 2300 hba's.
	The server is connected to a Ibm SVC 4.1 and the Ibm sdd driver
is installed.
	When we map a vdisk to the server we have to reboot the server
to get the new lun.
	According to the Ibm documentation we have to do a boot -r.
	After a reboot -r the existing vpaths are reshuffeled, which
causes that Disksuite doesn't recognise the filesystems anymore.
	For example, before the reboot vpath1=20Gb and vpath2=700Gb.
	After the boot -r, vpath1 = now vpath2 and vpath2=vpath1.

	To discover the new lun a normal boot (without -r) is fine.
	Without mapping a new vdisk a boot -r is also fine, it doesn't
reshuffle the vpaths.

	Anyone an idea?

	Many thanks in advance.
	Klaas
