OpenSolaris

Build 44

There is a bug related to network installations in this build:

    6453083  rmclient bug fix causes regression in addclient and removes /etc/ethers entry in snv_43 and snv44

There is a Workaround for the bug, please see section after description below.

Description

On our install server ins3525-svr, the /etc/ethers is a local file and we do not use NIS administer this.  We usually will update the /etc/ethers whenever we had new systems in the lab.

    If I do this on the ins3525-svr to add PXE client from any snv_43 or snv_44 images, it removes the ethernet address of the client:  
    root@ins3525-svr# pwd
    /export/nv/solarisdvd.nvx_dvd/latest/Solaris_11/Tools
    root@ins3525-svr#
    root@ins3525-svr# ls
    Boot                  addclient.sparc       rmclient
    Installers            addclient.x86         rmclient.sparc
    add_install_client    dial                  rmclient.x86
    addclient             rm_install_client     setup_install_server
    root@ins3525-svr# grep line3-colfax2 /etc/ethers
    00:e0:81:2a:a0:38 line3-colfax2
    root@ins3525-svr# ./addclient -d -e 00:e0:81:2a:a0:38 i86pc
    cleaning up preexisting install client "00:e0:81:2a:a0:38"
    cleaning /etc/ethers
    removing 00:e0:81:2a:a0:38 from ethers  
    To disable 00:e0:81:2a:a0:38 in the DHCP server, remove the entry with Client ID 0100E0812AA038
    copying boot file to /tftpboot/pxegrub.I86PC.Solaris_11-11  
    If not already configured, enable PXE boot by creating a macro named 0100E0812AA038 with:
      Boot server IP (BootSrvA) : 10.6.35.8
      Boot file      (BootFile) : 0100E0812AA038  
    root@ins3525-svr# grep line3-colfax2 /etc/ethers
    root@ins3525-svr# 

With the rm_install_client fix, we forget that addclient will call rmclient first and then call addclient.  Then the ethers entry for the client will be gone forever.  This causes corruption in the /etc/ethers and is a major headache for system administer.  I will replace the rm_install_client with the one from snv_42 until this problem is looked at.

This regression was caused by the fix to rmclient by bugid 4638062.
