Disk related Stuff
######### To find out from which disks OS booted From #########
#echo boot_string/s adb /stand/vmunix /dev/kmem
######### To find out if there are Stale in LVs #########
# /usr/sbin/vgdisplay -v awk '/LV Name/ { print $3 }' xargs /usr/sbin/lvdisplay -v grep -i -e "lv name" -e "lv status" -e stale -e '?'
######### To find out timestamp when the kernel was built/linked #########
# echo "linkstamp?s" adb /stand/vmunix
######### To get the LVM PVID and VGID from a disk #########
To get the LVM PVID and VGID from a disk. Please note that each unique ID consists of 2 longs (2 x 4 Bytes). The 1st long is a host ID (uname -i) and 2nd long is a timestamp. So the PVID tells you when some issued a pvcreate from what machine. The VGID does the same for the vgcreate.
PVID e.g::
# echo "0d8200?UY" adb /dev/dsk/c0t6d0
2008: 2010702141 2002 Jan 2 10:31:16
VGID e.g.:
# echo "0d8208?UY" adb /dev/dsk/c0t6d0
2010: 2010702141 2002 Jan 2 07:29:06
######### To get free space (Size in MB ) on all Volume Groups in a system #########
/usr/sbin/vgdisplay egrep -i 'VG NamePE SizeFree PE' awk 'BEGIN {print "VGname Free_space(MB)"} {a=$NF;getline;b=$NF;getline;c=$NF;print a,b*c}'
######### To get man pages in printable format #########
# man ls col –b ssp expand

Create a new software depot for patches
Creating a separate software depot for your patches is useful, when space is tight and patches have dependencies.
Assuming you have two patches PHNE_20000 and PHNE_20001. unshare all two patches by typing the following commands.
sh PHNE_20000
sh PHNE_20001
Next, we have to create a new software depot on the directory
/newdir/depot
mkdir /newdir/depot
swpackage -s PHNE_20000.depot -d /newdir/depot
Register your new depot on the sd-ux.
swreg -l depot /newdir/depot
Copy the next patch to the newly created software depot.
swcopy -s `pwd`/PHNE_20001.depot PHNE_20001 @ /newdir/depot
You are now ready to install your patches
swinstall -s /newdir/depot
And Villagers were
happy ever after....
