Why do you disable the HFS+ Journaling on the SSD?

My battery life also got worse when using the SSD. It's the price you pay for the performance, as in my case the Kingston SV100 SSD (1A) chews more power than the stock Hitachi HDD (0.6A).

How did installing the SSD affect your battery life? I'm seeing a large drop in battery performance since installing mine....

Sudheerrao29 & Jazzman, here is ur answer.

DAE4P – A 4 Gb/s point-to-point Fibre Channel disk enclosure. This is the standard disk enclosure for CX3 UltraScale series storage systems, as well as CX4 storage systems. The only difference between the two is the bezel on the front of the enclosure.

DAE2P – A 2 Gb/s point-to-point Fibre Channel disk enclosure. DAE2, DAE2-ATA, and DAE2P disk enclosures may all be present on CX series storage systems.

Re: LUN and VBUS Mapping for HP-UX

Bill Connolly — Fri, 29 Jul 2011 09:46:51 -0000

I have a script that will generate the mapping sintax for entering the starting address, and the two fa paths on dmx for host only requiring lun addressing. I was hoping that someone out their had the logic that would count from a starting vbus, target, lun and generate the sintax necessary to read a list of devices and output all the mapping commands. It was easy for just hosts like vmware, sun, window, aix. but hp with volumeset addressing is more complicated. thanks my email is bill.connolly@chick-fil-a.com
chick
here is the script to map a list of luns(in heads.out) to be used with symconfigure

/support/storage/bill/scripts-132# cat createmap.out#/usr/bin/ksh# arguements# arg 1 = starting lun# (Alpha must be uppercase)# arg 2 = first FA port in ##:## arg 3 = second FA port in ##:###set -xif [ $# -ne 3 ]then echo "Usage: `basename $0` StartingLun FirstFA SecondFA " exitfi
n=`echo "obase=10;ibase=16; $1;" |bc`for i in `cat heads.out`do outn=`echo "obase=16;ibase=10; $n;" | bc` echo "map dev $i to dir $2, lun=$outn;" echo "map dev $i to dir $3, lun=$outn;" echo n=`expr "$n" "+" 1`done

If you know how to do this for hpux. Please send me a copy to bill.connolly@chick-fil-a.com. thanks again.

Re: HDS Bloggers Day – Day 1 – Session 03/23/2011

Chadwick James King — Mon, 25 Jul 2011 12:40:27 -0000

Devang,
I hope to learn more about the HDC in our own environment. I am new in some ways and was wondering if you or anyone has actually seen the vCenter plug-in for HDS systems. The biggest problem we are seeing is that when we are doing migrations and LUN provisioning they cannot use a naming convention to reference between the Datastores and the LUNs provisioined. I know there are other tools out there that can help with this and I am sure it is somewhere out there but it seems like there are some missing links from here to there. Any help would be appreciated.

# symld –g newtgtdg rename DEV001 NEWVOL1

You are making the DEV001 on remote host to see as a similar to local ( which will be easy for understanding )
