Post subject: | AIX script to list 3Par hdisks/LUN #/Volume Group |
We wanted an easy way to list the 3Par luns on AIX and see what they were assigned to, specifically which volume group or if they were raw disks in Oracle ASM. We provision multiple tiers of storage to database hosts. FC 15k disks are used for the database drives, and SATA is used for the flash recovery area (backup to disk). Communication between storage admin and AIX admin can get confusing when trying to identify which luns are the SATA for backups. Our local AIX team wrote these scripts to make this task easier. Root not required. You should have your AIX admin evaluate these scripts before you install and run them on their systems. The first script is a modified lspv that lists all physical disks and displays which VG they are assigned to or if they belong to Oracle ASM. lspv2 Code: #!/bin/ksh if [ $# -eq 0 ] then touch /tmp/ASM_lspv.out /usr/sbin/lspv > /tmp/lspv.out for i in `grep None /tmp/lspv.out | awk '{print $1}'` do ls -l /dev/r${i} | grep oracle > /dev/null 2>&1 if [ $? -eq 0 ] then echo "$i" >> /tmp/ASM_lspv.out fi done cat /tmp/lspv.out | grep -vwf /tmp/ASM_lspv.out > /tmp/lspv1.out 2>/dev/ null cat /tmp/lspv.out | grep -wf /tmp/ASM_lspv.out | sed 's/none None/ASM Disk For Oracle ASM Disk act ive/' > /tmp/lspv2.out 2>/dev/null cat /tmp/lspv1.out /tmp/lspv2.out rm -f /tmp/ASM_lspv.out rm -f /tmp/lspv.out rm -f /tmp/lspv1.out rm -f /tmp/lspv2.out else /usr/sbin/lspv $* fi The second script depends on the first script, and builds a list of just 3par disks, LUN ID, and VG assignment. ls3par Code: echo "Disk\tLUN\tVG Name" for i in `lsdev -Cc disk | grep -i 3par | awk '{print $1}'` do LUNID=`lsattr -El $i | grep -i lun | awk '{print $2}' | awk -F"x" '{print $2}' | awk -F"000000000000$" '{print $1}'` ((mydec=16#$LUNID)) VGNM=`/opt/local/bin/lspv2 | grep -w $i | awk '{print $3}' | sed 's/Disk/ASM Dis k/g'` echo "$i\t$mydec\t$VGNM" >> /tmp/3par.$$ done cat /tmp/3par.$$ | sort -n +1 2>/dev/null rm -f /tmp/3par.$$ Example Output wrote: Disk LUN VG Name

I like this. When I implement this, I will make a small change to add some randomness to the filenames that get the redirects in /tmp rnd=$RANDOM # generate a random number and assign it to a variable touch /tmp/ASM_lspv.${rnd}.out /usr/sbin/lspv > /tmp/lspv.${rnd}.out etc... That will prevent an unprivileged user from doing: ln -s /etc/passwd /tmp/lspv.out I'd hate to have to clean up the mess after effectively: lspv > /etc/passwd |

You can also use HP 3PARinfo on AIX (and HPUX, Solaris, Linux, VMware & Windows) to get this info without resorting to script writing. It's a lightweight tool installed into the OS. Very handy for giving a common understanding of LUN info if there are separate OS/Application Admins and Storage/SAN Admins who sometimes might talk at cross-purposes. Download for FREE from HP's software depot: https://h20392.www2.hp.com/portal/swdep ... r=3PARinfo Latest version is now 1.3. See release notes and user guide for more info on installation, command syntax, etc. |
