CentOS 4.x and OMSA 6.1 - Update breaks IPMI --FIXED

[Hostmaster]

Hi All,

I have a CentOS 4.7 server which automatically downloaded and installed OMSA 6.1
last night after it was released onto the repo. I noticed this morning that it
had broken all SNMP hardware checks, and on investigation this was caused by the
fact that IPMI was not running.

 

A "srvadmin-services.sh start" came back with:

 

Starting Systems Management Device Drivers:

Starting dell_rbu: Already started                         [  OK  ]

Starting ipmi driver: Unsupported version                  [FAILED]

Starting Systems Management Device Drivers:

Starting dell_rbu: Already started                         [  OK  ]

Starting ipmi driver: Unsupported version                  [FAILED]

Starting DSM SA Shared Services:                           [  OK  ]

 

"Unsupported version"? Hmm.... It worked OK yesterday with 5.5! I started
pulling things apart and found that it was failing when starting IPMI in
/etc/rc.d/init.d/instsvcdrv. A manual run of that script provided:

 

/etc/rc.d/init.d/instsvcdrv start

instsvcdrv_oihapicfg_validate_addheader()

Starting Systems Management Device Drivers:

Starting dell_rbu: Already started                         [  OK  ]

Starting ipmi driver: CheckOpenIPMIVersion: FAILED to determine OS

CheckOpenIPMIVersion: kernel version minimum is: 2.6.15

CheckOpenIPMIVersion: running kernel version is: 2.6.9-78.0.5.ELsmp

CheckOpenIPMIVersion: failed: kernel patch version < minimum

instsvcdrv_oihapicfg_validate_addheader()

Unsupported version                                        [FAILED]

 

Aha! The script is failing to determine which OS the server is running, and then
using the kernel requirement of 2.6.15 as a fallback/failsafe. CentOS 4.7 is
still on 2.6.9, hence the "Unsupported Version".  RHEL4 is however a "supported
OS" for OMSA6.1, so what is going on here? Obviously the script is failing to
pick up on the fact that it is Centos 4.7.

 

vi /etc/rc.d/init.d/instsvcdrv

 

    365         ##elif [ ! "`grep 'Nahant' /etc/redhat-release 2>/dev/null`" ==
"" ];

    366         then

    367                 debugprint "${l_fname}: OS is RHEL4"

    368                 l_maj_ckey=${OPENIPMI_RHEL4_VERMAJ_CONFIG_KEY}

    369                 l_maj_dflt=${OPENIPMI_RHEL4_VERMAJ_DEFAULT}

    370                 l_min_ckey=${OPENIPMI_RHEL4_VERMIN_CONFIG_KEY}

    371                 l_min_dflt=${OPENIPMI_RHEL4_VERMIN_DEFAULT}

    372                 l_modext=".ko"

 

But my /etc/redhat-release doesn't contain "Nahant"....

 

cat /etc/redha-release

CentOS release 4.7 (Final)

 

A quick amendment of line 365:

 

365        elif [ ! "`grep 'CentOS release 4.' /etc/redhat-release 2>/dev/null`"
== "" ];

 

And it works:

 

srvadmin-services.sh start

Starting Systems Management Device Drivers:

Starting dell_rbu:                                         [  OK  ]

Starting ipmi driver: CheckOpenIPMIVersion: OS is RHEL4

CheckOpenIPMIVersion: minimum version is 33.13

CheckOpenIPMIVersion: version >= minimum

instsvcdrv_oihapicfg_validate_addheader()

Already started                                            [  OK  ]

Starting Systems Management Data Engine:

Starting dsm_sa_datamgr32d:                                [  OK  ]

Starting dsm_sa_eventmgr32d:                               [  OK  ]

Starting dsm_sa_snmp32d:                                   [  OK  ]

Starting DSM SA Shared Services:                           [  OK  ]

 

I hope someone else finds this useful, or that the nice folks at Dell can please
put a clause into this script to identify Centos 4 using this string and
classify it as RHEL4 equivalent. FWIW, I have tested OMSA 6.1 on some CentOS 5.3
servers, and they all seem unaffected.
