Upgrade Considerations for OSIM

While upgrading ITCM from R12.5 SP1 FP1 CentOS patch (R055831) or R12.5 SP1 FP1 C1 to CA ITCM Release 12.8, perform the following steps:

• Update the existing Linux-Based (LinuxPE) boot image.
• Update the existing RHEL5.x and RHEL6.x LinuxPE-based OS images.
• Update any existing OS images (earlier supported with WinPE and Dosx) which is now supported with LinuxPE. After you update the existing OS image, ensure that the value of InstallDrive boot parameter is sda, sdb.
• Change the value manually to the one supported by the OS images.

Note: Specify the InstallDrive boot parameter about the use of local disk for the OS installation. The default value is empty and first available local disk is used for OS Installation.

You can add a disk in the following ways:

• Add the disks from the DSM explorer like sde, sdf for more than four (4) disks.
• Modify the file OS.def under the OSIM IPS (CA\DSM\osimips\os-template\camenu) folder.

See the new definition for the InstallDrive boot parameter for LinuxPE-based OS images:

[InstallDrive]

Type=MapListExt

Trans=yes

MaxLength=128

Comment=Disk to install the OS like sda or sdb or sdc. 

item=sda

item=sdb

item=sdc

item=sdd
