upgrade the OS ( v2 to v3) By SW Depot

Scenario:

We use New disk to create SW Depot. From which we have to upgrade the OS ( v2 to v3)  .

Insert the New Disk

Use ioscan to check disk is install or properly claimed

# ioscan –fC disk

Use insf to create the new device files (cXtXdX)

# insf –C disk

Use the pvcreate command to prepare the identified disk, using the character disk device file. Option -f will forcefully recreate the LVM headers on the disk.

# pvcreate -f /dev/rdsk/cXtXdX

Physical volume "/dev/rdisk/disk40" has been successfully created.

 

#mkdir /dev/vg01

Change the owner of the directory /dev/vg01 to root:root.

#chwon root:root /dev/vgname

Change the permission of the directory /dev/vg01 to 755

#chmod 755 /dev/vgname

Create the Creating group device file by using the standard mknod command.

#mknod /dev/vg01/group c 64 0x010000

Change the ownership of the group file to root:sys.

#chwon root:sys   /dev/vgname/group

Change the permission to 640.

#chmod 644 /dev/vg01/group

#vgcreate

For example (output):

Increased the number of physical extents per physical volume to 17501.

Volume group "/dev/vg01" has been successfully created.

Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf

Use the lvcreate command to create a logical volume.

Note: The -L option is used to specify the total size of the logical volume in MB and the -n option is used to provide a non-default name for the logical volume.

#lvcreate –L 25600 -n lvol1  vg01

 

NOTE:- LV size should be more then 8 GB.

For example (output):

Logical volume "/dev/vg01/lvol1" has been successfully created with

character device "/dev/vg01/rlvname".

Create a new file system

we will create the new file system on the lvol1 logical volume and mount it on /hpux directory. We will add this to /etc/fstab.

Create a new file system using the newfs command.

# newfs -F vxfs /dev/vg01/rlvoll

version 6 layout

16384 sectors, 16384 blocks of size 1024, log size 1024 blocks

largefiles supported

Create a data directory using the mkdir command.

# mkdir /data

Mount datavol on /hpux directory.

# mount /dev/vg01/lvol1 /hpux

 Creating a depot

Find the CD-ROM device file name:

#ioscan -fnC disk | more

NOTE : A typical CD-ROM device name is: /dev/dsk/cXtXdX

Create the directory /cdrom under root(/):

#mkdir /cdrom

Mount the CD onto the /cdrom directory as a file system.

For example:

mount /dev/dsk/cXtXdX /cdrom

Merge all products on the mounted CD to the target depot, for example /hpux

# swcopy -s /cdrom \* @ /hpux

 Unmount the CD from directory /cdrom:

 # umount /cdrom

Listing Registered Depots swlist can display lists of registered depots residing on a host. To do this, use combinations of the -l depot option.

To list all depots on the local host, type:

# swlist -l depot

NOTE :- If its not registered Depot then run

# swreg -l depot /hpux

# swlist –l depot à check your depot 

Using swinstall, install the latest version of the Update-UX product on the target system:

#swinstall -s /hpux Update-UX

NOTE: Make sure you use the correct case to install the Update-UX product (in title case).

This product contains the update-ux command (lowercase).

Upgrade the OS with UPDATE-UX

#update-ux  -p -s /hpux HPUX11i-VSE-OE T1335DC

#update-ux –s HPUX11i-VSE-OE T1335DC
