Chapter 7. Installing RHEL 6 on the cloner 119

7.1.6 Working around a known issue

Important: If the minidisks 100-102 (dasdb-dasdd) have not been formatted for Linux by

dasdfmt before this installation, you should see the window shown in Figure 7-5 on

page 118. However, there is a known issue in RHEL 6 where this window does not open

and you do not have the ability to format the disks through the installer. If you proceed

without formatting the disks with dasdfmt, the installation process will fail later.

If this is the case, perform the following steps:

1. Start a second SSH session, this time logging in as root:

Welcome to the anaconda install environment 1.2 for zSeries

򐂰 Issue the lsdasd command. The three minidisks should be dasdb, dasdc, and dasdd:

# lsdasd

Bus-ID Status Name Device Type BlkSz Size Blocks

0.0.0101 active dasdc 94:8 ECKD 4096 2347MB 600840

0.0.0102 active dasdd 94:12 ECKD 4096 2347MB 600840

0.0.0300 active dasde 94:16 FBA 512 256MB 524288

0.0.0301 active dasdf 94:20 FBA 512 512MB 1048576

򐂰 Format the minidisks in parallel with the following for loop:

# for i in b c d

> do

> dasdfmt -b 4096 -y -f /dev/dasd$i &

> done

򐂰 You may need to press Enter to see the jobs in the background complete. After the for

loop completes, return to the VNC session and complete the installation.
