We have some limitations and
have to replace all HITACHI
I am not sure how I am going
to do it it’s a big task near about 40 TB data migration from UNIX point of
view.
Still there is no proper plan in place I don’t have any one here with me to deal with this and time lines are really tight.

There are many dependencies
from AIX LVM too I should need to and read everything about storage management.
Now I have reviewed it and finally
come up with a direction.
- Disks are not coming from VIO (for my current
projects other wise they are from vio only )
- My AIX client is running on 53-09-04 and it’s recommended
to upgrade it to TL 11 (as it’s not necessary I am skipping it )
- There are ssd drivers installed on my AIX clients
Where are SVC needs sddpcm drivers.
- Will have to install them first – which needs
downtime.
- Downtime approx 6 hrs.
- After installation of sddpcm I will have to start
migration activity.
- I have around 900 disks and have to migrate to
svc.
- There are 5 vgs and 3 are scalable and other 2
are big I may have to convert them to scalable.
- And lots of things.
- I will post here how I am handling this.
- I would not be able to post any specific
information every thing will be general; All server name/ Ip’s will be
replace by dummy values.
- I was having a file systems list around 300 and I
wanted to know all details as below,
Filesystem_name <space>
LV_name<space>VG_name
So I
can start further planning.
I
have written a small for loop to do this file /tmp/d will contain list of
filesystems.
for i in `cat /tmp/d`
do
w=`df -g $i|awk '{print $1}'|tail -1|sed 's/\/dev\///g'`
vg=`lslv $w|head -1|awk '{print $6}'`
echo "$i $w $vg"
sleep 3
done
to be cont..
