Get WWN tree info for an hba

rdircio — Mon, 31 Oct 2011 02:58:07 +0000

To get all the wwns attached to an hba you can use this
# cfgadm -al -o show_FCP_dev | egrep ‘disk|tape’

create user’s homes from the entries at /etc/passwd

rdircio — Sat, 29 Oct 2011 23:52:24 +0000

i don’t like to do a # cat /etc/passwd and manually create the users and chown their dirs… So, this is a one liner:

# grep -i home /etc/passwd | awk -F: ‘{print “mkdir ” $6 ” ; chown ” $1 ” ” $6 }’ > somefile; chmod 755 somefile;./somefile 183/433

scan for new disks inside a linux vmware vm

rdircio — Fri, 28 Oct 2011 17:22:10 +0000

Just do this:

ls /sys/class/scsi_host/ | while read h;do echo “- – -” > /sys/class/scsi_host/$h/scan;done

Change timezone in solaris

admin — Sun, 01 Jan 2012 05:51:50 +0000

Edit /etc/TIMEZONE and use one of the typical:
US/Eastern
US/Central
US/Mountain
US/Pacific
or look for an appropriate timezone in /usr/share/lib/zoneinfo
After this reboot your server with shutdown or init.

is your solaris running on 64bit or/and 32bit?

Just type
# isainfo -v

Configure the VCS hagui service

admin — Sat, 31 Dec 2011 05:51:50 +0000

for those who feel comfortable with the hagui in Veritas Cluster, and cannot use it because you don’t have the daemon
running, you must add this section to your /etc/VRTSvcs/conf/config/main.cf:
group ClusterService (
SystemList = { hst101 = 0, hst102 = 1 }
AutoStartList = { hst101, hst102 }
OnlineRetryLimit = 3
Tag = CSG
)
IP webip (
Device = eth0
Address = “172.20.162.15″
NetMask = “255.255.254.0″
)
Where you need to change “hst101″ and “hst102″ to the hostnames of your nodes, and configure your
network interface accordingly.
Edit VCS main.cf using vi
Sometimes you need to edit your veritas cluster configuration file “main.cf” and you feel the urge to do it using vi, here’s
how to do it:
hastop -all
cp main.cf main.cf.copy
vi main.cf
hacf -verify /etc/VRTSvcs/conf/config
hacf -generate /etc/VRTSvcs/conf/config
hastart

Stats script based on top for Solaris

admin — Fri, 30 Dec 2011 21:51:50 +0000

you can do this
(date “+%d %m %H %M %S %Y”
/usr/local/bin/top -b | head -4) >> /tmp/top.txt
Then parse and collect:
echo “date,time,loadavg1,loadavg5,loadavg10,processes,sleeping processes,on cpu,cpu idle,cpu user,cpu
kernel,cpu iowait,swap,memory,free mem,total swap,free swap”
cat /tmp/top.txt |nawk ‘ORS=NR%5?” “:”n”‘ | tr -d ‘[:alpha:]‘| sed ‘s/;//g;s/:/ /g;s/,//g’ | awk ‘{ print
$1″/”$2″/”$6″,”$3″:”$4″:”$5″,”$8″,”$9″,”$10″,”$17″,”$18″,”$19″,”$20″,”$21″,”$22″,”$23″,”$24″,”$25″,”$26″,”$27″,”$28
}’
this builds a csv you can import in a spreadsheet
