EMC 300-000-978 REV A03 manual Recovery, Procedure

Configuring a PowerPath Boot Device on Solaris

	6.	Using a text editor such as vi, make the following changes to the
		/etc/system file:
		• Add this line above the forceload: drv/emcp statement:
		forceload: drv/sd
		• Add this line below the forceload: drv/emcp statement:
		rootdev: /pseudo/emcp@6:a,blk
		The /etc/system file now includes the following lines:
		forceload: drv/sd
		forceload: drv/emcp
		rootdev: /pseudo/emcp@6:a,blk
	7.	Using a text editor such as vi, edit the /etc/vfstab file,
		replacing each native partition (c#t#d#s#) for the boot device
		with an emcpower partition name. In this example, you would
		replace c1t6d0s0 with emcpower6a. You must change both the
		/dev/dsk and /dev/rdsk entries.
	8.	Restart the host. Enter:
		reboot
Recovery	If you cannot boot the host after configuring the PowerPath device as
Procedure	the boot device, you may have made a typing error when editing the
	/etc/system and /etc/vfstab files. To recover:
	1.	Insert the Solaris Operating System CD-ROM into the host’s
		CD-ROM drive.
	2.	At the ok prompt, enter:
		boot cdrom –s
	3.	Mount the storage system boot device that is experiencing the
		problem. For example, enter:
		mount /dev/dsk/c1t6d0s0 /a
	4.	Enter:
		TERM=sun-cmd
		export TERM
	5.	Check the /etc/system and /etc/vfstab files against the
		changes you made to these files when you set up multipathing to
		the storage system boot device. Use a text editor such as vi to
		correct any problems you find.
