vgcreate how ???

[David Willams]

I am using the following script to create VG's

for V in 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15
do
mkdir /dev/vg${V}
mknod /dev/vg${V}/group c 64 0x${V}0000
done


Now how I include vgcreate in it...


for V in 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15
do
vgcreate –s 16 /dev/vg${V} /dev/disk/disk40 -----???? How to Include this line...

my ioscan looks like below

take a close look at /dev/rdisk/disk64 -> you should not specify "raw disk" device file while create vg

i hope some typ0 error -> "/dev/rdisk/disk64"

should /dev/dsk/disk64

[David Willams]

the following worked,
but I have around 95 VG's to create ... could you please suggest me a better way

Hi

Ok, its obvious from your last two postings that your new to this. For this problem, forget it. If you want to write a script, which is 100% right for documentation puposes, especially if you work for a Pharm. or DoD firm, that gets audited by either the FDA or the Military: If you want to write a script then you have to get rid of the loops and write each command out, taking into consideration the PV Links Round Robin Algorithm.

c0t1d0 vg01
c1t1d1
c1t1d2 vg01 -or- vg02
c0t1d4

For load balancing and better Disk I/O performance, you make controller 0 your first primary disk in a volume group, and then you make controller 1 your first primary disk.

You've got like 100 disks, so you have to map them out on paper first, ending up with a 150 line script. Which is a good thing, not a bad thing, because now you can show it to mgmt. in case.

Load balancing is also achieved with EMC Power Path, Secure Path, is native to 11.31: There are other applications that superceed PV Links. I still do it this way despite having Power Path. Why? Power Path doesn't update /etc/lvmtab so you ended up not knowing what your Inventory of Free disks are, unless you use SAM.

What is your O/S version and do you have other Load Balancing applications? You have to consider this before creating volume groups.

That helps... Thanks Michael
