Removing PowerPath Control Over a Boot Device
If your PowerPath installation uses a storage system device as the
boot device, use the following procedure to remove PowerPath 4.0
control over the boot device:
1. Determine whether the boot path from the host to the storage
system has changed since the storage system boot device was
configured.
a. Examine the
/etc/vfstab.no_EMCpower file to identify the
native name for the boot device; for example, c1t6d0s0. Enter:
cat /etc/vfstab.no_EMCpower
b. Determine the boot path associated with this native device.
For example, enter:
ls -al /dev/dsk/c1t6d0s0
An example of a boot path is
/pci@1f,4000/scsi@4/disk@6,0.
c. Compare the boot path from step 1.b. with the original boot
path. Enter:
cat /etc/nvramrc.orig
2. If the boot path listed in step 1.b. differs from that in the
nvramrc.orig file, update the boot path to reflect the value listed
in step 1.b. For example, enter:
eeprom nvramrc=”devalias storagedisk /pci@1f,4000/scsi@4/disk@6,0”
3. Verify that the boot path was changed to the new value. Enter:
eeprom
4. Restore the versions of /etc/system and /etc/vfstab that do
not contain references to PowerPath. Enter:
cp /etc/system.no_EMCpower /etc/system
cp /etc/vfstab.no_EMCpower /etc/vfstab
