Error description

SSM 4 ABSTRACT: On some Solaris Systems Disks the SSM can mark
disk devices as down incorrectly.
DESCRIPTION: The SSM on some Solaris machines will mark disks as
down in the hrDeviceTable. This can happen even though the disk
devices are operational.

Local fix

Await workaround using inivar


The INIVAR would be a new variable.
It would allow customers who experience this issue to "override"
the string that we map with. It wouldn't be automatically set.
and wouldn't be enabled by default.

Basically it would allow us to fix this particular case with a
configuration option.

So in order to deploy the fix the customer would a) apply the
patch b) update their init.cfg

Problem summary

****************************************************************
* USERS AFFECTED:                                              *
* Users of the SSM HostRes table on Solaris where the name of  *
* a disk instance in kstat does not match the device name in   *
* libdevinfo.                                                  *
****************************************************************
* PROBLEM DESCRIPTION:                                         *
* The SSM HostRes table will report disk devices as down on    *
* some Solaris operating systems. This is caused by the name   *
* that is used in kstat for the disk not being the same as the *
* name in used by the libdevinfo library.                      *
****************************************************************
* RECOMMENDATION:                                              *
* Upgrade to SSM 4.0.1                                         *

Problem conclusion

This issue is resolved by the addition of a Inivar that allows
the user to explicitly map between the kstat and libdevinfo
values. This inivar is called SolarisDiskValue.  Information on
how to use it is as follows:

When hostres cannot automatically map device names, this inivar
maps the strings found in kstat to the matching device in the
libdevinfo tree.

The format is:
SolarisDiskValue=kstat_device_class=devinfo_device_class[,kstat_
device_class=devinfo_device_class,kstat_device_class=devinfo_dev
ice_class,...]

To find the value to map to, find the class name of the disks.
1. Look at hrDeviceDescr to get the kstat value. For example, in
this description which contains the serial number of the device
sd0: HITACHI H106060SDSUN600G, the kstat device class is SD.
2. Search the output of prtconf for the same serial number to
get the devinfo value. For example,
    disk, instance #0 (driver not attached)
        Hardware properties:
            name=?inquiry-revision-id? type=string items=1
                value=?A2B0?
            name=?inquiry-product-id? type=string items=1
                value=?H106060SDSUN600G?
            name=?inquiry-vendor-id? type=string items=1
                value=?HITACHI?
gives you a devinfo device class of disk.
In this example, SolarisDiskValue=sd=disk
