I’m not sure if i will add this cert on my CV.  Free cert without exam?  Bad idea i guess..

To validate your LPIC go to https://cs.lpi.org/caf/Xamman/certification and apply for Novell CLA certification at http://practicum.novell.com/LPI2CLAForm.php. Fill out the form, provide your LPI ID and verification code. Allow 1 business day before they send your pdf certification stating that you are a certified SUSE Linux Enterprise 11 admin!!!

Initialization

Disk initialization

/usr/lib/vxvm/bin/vxdisksetup -iv [device_tag][attributes]

Example:

#/usr/lib/vxvm/vxdisksetup -iv c2t0d0

Creation
Create initial disk group

vxdg init [diskgroup] [disk_name=device_tag]

Example:

#vxdg init newdg disk1=c2t0d0

Add more disk to the Disk Group

vxdg -g [disk_group] adddisk [disk_name=device_tag]

Example

#vxdg -g newdg adddisk disk2=c2t1d0

Volume Creation

Concatenated Volume

vxassist -g [disk group] make [volume_name] [size]

Example

#vxassist -g newdg make newvol 500m

Concatenated Volume by specifying the disk

# vxassist -g newdg make newvol disk02 disk03

Striped Volume

vxassist -g [disk group] make [volume_name] [length] layout=stripe ncol=n stripeunit=size

Example

#vxassist -g newdg make newvol 500m layout=stripe

Mirrored Volume

#vxassist -g newdg make newvol 500m layout=mirror

Removing
–loading–

Download the updated SUNWrge package, this holds the driver for rge

http://www.aplis.cz/SUNWrge.tar.gz

My Jumpstart image is shared thru NFS in /installer directory

#cd /installer/boot

Create a temporary miniroot directory

#mkdir x86.miniroot-rge.unpacked

Unpack the existing miniroot to the temp miniroot directory

#/boot/solaris/bin/root_archive unpack ./x86.miniroot ./x86.miniroot-rge.unpacked

Remove the existing SUNWrge package

#pkgrm SUNWrge

Add the updated SUNWrge package

#cd /export/home/john
#gunzip SUNWrge.tar.gz
#tar xvf SUNWrge.tar
#pkgadd -d . SUNWrge

Check the new aliases

#grep rge /etc/name_to_major /etc/driver_aliases
/etc/driver_aliases:rge “pci10ec,8169″
/etc/driver_aliases:rge “pci10ec,8110″
/etc/driver_aliases:rge “pci10ec,8168″
/etc/driver_aliases:rge “pci10ec,8111″

Remove the existing rge driver in the jumpstart miniroot

#cd /installer/boot
#/usr/sbin/rem_drv -b ./x86.miniroot-rge.unpacked/ rge

Add the new driver

#/usr/sbin/add_drv -b ./x86.miniroot-rge.unpacked  -n -v -m ‘* 0600 root sys’ -i ‘”pci10ec,8169″ “pci10ec,8110″ “pci10ec,8168″ “pci10ec,8111″‘ rge

Reboot client to install driver.
Driver (rge) installed.

Backup original miniroot

#mv x86.miniroot x86.miniroot.orig

Compress the new Jumpstart miniroot

#/boot/solaris/bin/root_archive pack ./x86.miniroot ./x86.miniroot-rge.unpacked/
