I have never wondered where is the mapping of the link names to physical device path display under
Code:
dladm show-phys
until today.
fmadm list reported nic port failure and i am trying to mapped it to the correct linkname in dladm show-link / dladm show-phys to see if the link is actually up and running or down.
I remember it used to be under /etc/dladm/ , so i went to list it
Code:
ls -la /etc/dladm/
total 29
drwxr-xr-x 2 netadm netadm 6 Oct 29 17:02 .
drwxr-xr-x 88 root sys 181 Oct 29 20:56 ..
-rw-r--r-- 1 netcfg netadm 1296 Jun 14 16:06 datalink-Automatic.conf.obsolete
-rw-r--r-- 1 netcfg netadm 512 Sep 7 02:38 datalink-DefaultFixed.conf.obsolete
-rw-r--r-- 1 netcfg netadm 1564 Oct 27 14:30 datalink.conf.obsolete
-rw-rw---- 1 dladm netadm 186 Oct 27 14:08 secobj.conf
Everything has a .obsolete tag behind and i remember that i have recently updated to 11.4
So i went back to mount my old 11.3 boot environment and realize those files in the same path doesn't have a .obsolete behind.
So long story short,
a) do you guys on 11.4 have these .obsolete files as well ?
b) if these files are obsolete, where does 11.4 store these link-to-device information now ?

Noob

hi experts,
i had create wrong symbolic link on my server use this ln -s /opt/EBS /export/home/EBS, cause i had create an EBS directory on /export/home/EBS/ so the command ln create EBS directory on /export/home/EBS/EBS/....
how to remove the EBS that had created by ln command ?

Thanks to DukeNuke for the suggestion of dladm before. I was able to upgrade my machine to Solaris 10. I am checking out the sue of dladm, but I am a bit confused. In order to team 2 NIC ports together on my qud ethernet card do I just do this:
dladm create aggr -d ce0 -d ce1 key

Can anyone reference me where I can find info
or if someone knows the mapping of Solaris kernel parameters to HP-UX 11i v2 O/S on Integrity server?
Your response would be greatly appreciated.

Hi All,
Can any body guide me towards the x86 link? I need to understand the disk slice and booting sequences in x86 as I have to give my SA1.
Please help. (4 Replies)

Is there a way by which we could map Oracle SGA memory into physical files in solaris.
We could find these physical files in /dev/shm/ folder in linux environment but they are missing in solaris. (1 Reply)

igb
igb(7D) Devices igb(7D)NAME
igb - Intel 82575 1Gb PCI Express NIC Driver
SYNOPSIS
/dev/igb*
DESCRIPTION
The igb Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider
Interface, dlpi(7P), on Intel 82575 Gigabit Ethernet controllers.
The igb driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support, and error
recovery and reporting.
The igb driver and hardware support auto-negotiation, a protocol specified by the 1000 Base-T standard. Auto-negotiation allows each
device to advertise its capabilities and discover those of its peer (link partner). The highest common denominator supported by both
link partners is automatically selected, yielding the greatest available throughput, while requiring no manual configuration. The
igb driver also allows you to configure the advertised capabilities to less than the maximum (where the full speed of the interface is
not required), or to force a specific mode of operation, irrespective of the link partner's advertised capabilities.
APPLICATION PROGRAMMING INTERFACE
The cloning character-special device, /dev/igb, is used to access all Intel 82575 Gigabit devices installed within the system.
The igb driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of igb instances and for igb
instances to be aggregated. See dladm(1M) for more details.
You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (PPA). The PPA ID is interpreted as
an unsigned integer data type and indicates the corresponding device instance (unit) number. The driver returns an error (DL_ERROR_ACK) if
the PPA field value does not correspond to a valid device instance number for the system. The device is initialized on first attach and de-
initialized (stopped) at last detach.
The values returned by the driver in the DL_INFO_ACK primitive in response to your DL_INFO_REQ are:
o Maximum SDU is 9000.
o Minimum SDU is 0.
o DLSAP address length is 8.
o MAC type is DL_ETHER.
o SAP (Service Access Point) length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP
component within the DLSAP address.
o Broadcast address value is the Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular SAP with the stream.
CONFIGURATION
By default, the igb driver performs auto-negotiation to select the link speed and mode. Link speed and mode can be any one of the follow-
ing, (as described in the IEEE803.2 standard):
1000 Mbps, full-duplex.
100 Mbps, full-duplex.
100 Mbps, half-duplex.
10 Mbps, full-duplex.
10 Mbps, half-duplex.
The auto-negotiation protocol automatically selects speed (1000 Mbps, 100 Mbps, or 10 Mbps) and operation mode (full-duplex or half-duplex)
as the highest common denominator supported by both link partners.
Alternatively, you can set the capabilities advertised by the igb device using ndd(1M). The driver supports a number of parameters whose
names begin with adv_ (see below). Each of these parameters contains a boolean value that determines if the device advertises that mode of
operation. For example, the adv_1000fdx_cap parameter indicates if 1000M full duplex is advertised to link partner. The adv_autoneg cap
parameter controls whether auto-negotiation is performed. If adv_autoneg_cap is set to 0, the driver forces the mode of operation
selected by the first non-zero parameter in priority order as shown below:
(highest priority/greatest throughput)
adv_1000fdx_cap 1000Mbps full duplex
adv_100fdx_cap 100Mpbs full duplex
adv_100hdx_cap 100Mbps half duplex
adv_10fdx_cap 10Mpbs full duplex
adv_10hdx_cap 10Mpbs half duplex
(lowest priority/least throughput)
All capabilities default to enabled. Note that changing any capability parameter causes the link to go down while the link partners renego-
tiate the link speed/duplex using the newly changed capabilities.
