Since customer
does not remove the foreign devices before upgrade to version 5.0 as recommend
by the installation guide(page 74-78 Veritas Storage Foundation installation
guide 5.0 for Solaris), the disk pubpath are pointed to
pubpaths:
block=/dev/vx/dmp/emcpowera8 char=/dev/vx/rdmp/emcpowera8
But on the disk
itself, the information is defined on slice 0 as below:
public: slice=0
offset=2049 len=142784511 disk_offset=0
private:
slice=0 offset=1 len=2048 disk_offset=0
Since the disk
is defined as simple device before and with the contrast of information of the
pub and private path, VxVM now change its status from online to online aliased
flag.
Now run the
following command to see whether devices had been added as foreign
devices
#vxddladm
listforeign
The Paths
included are

Run fdisk -l on

Now add the
devices back to as foreign devices
#vxddladm -a
addforeign path=/dev/emcpowera
If vxconfigd
can be killed , please run
#vxconfigd -k
or
run
# vxdctl enable
Run the
following command
#vxdisk
-oalldgs list

emcpowerc

Make a backup
of partion table for emcpowerb and emcpowerc first and add these devices as
power devices
#vxddladm -a
addforeign path=/dev/emcpowerb
#vxddladm -a
addforeign path=/dev/emcpowerc
Kill vxconfigd
if possible or run vxdctl enable. The diskgroup now should be import
automatically and check to see whether all volumes are enable /active before
mounting these file systems.
