Greetings Forumers!!
I was given a T2000 with one, dual port, HBA card. The card had one fiber connection to the SAN and the former admin enabled MPxIO.
Yesterday, I learned that the other port was connected to the same SAN. This system is in another city so I don't have physical access to... (1 Reply)

:confused:
Last week I read that VxVM won't work with MPxIO (i don't recall the link) and that it should be unconfigured when installing VxVM. Today I read that VxVM works in "pass-thru" mode with MPxIO and DMP uses the devices presented by MPxIO.
If I create disks with MPxIO and use VxVM to... (1 Reply)

Hi,
I have a quick question.
How can I see MPXIO statistics (like errors, how many I/O|throuput per path, ....) on Solaris 10? Does maybe a ready dtrace script exist (I do not have the knowledge to write one myself)?
I would be happy if somebody knows some good documentation/links (with... (1 Reply)

Hi,
I'm new to solaris and just installed solaris 10. For some reason I can't resolve stuff. I installed it with the option to use dns. My routing is correct. (I can ping stuff outside my subnet).

ifc_disable_mgmt_lun(5) File Formats Manual ifc_disable_mgmt_lun(5)
NAME
ifc_disable_mgmt_lun - select whether or not management luns are discovered in the legacy representation of mass storage devices
VALUES
Failsafe
Default
Allowed values
Enable discovery of management luns for array devices.
Disable discovery of management luns for array devices.
Recommended values
DESCRIPTION
Management luns provide the means to access the control ports of Fibre Channel disk arrays. They are represented in both the legacy and
the agile view of storage devices. The legacy representation of a management lun is typically created under a separate virtual extension
bus node. The entry for a legacy management lun looks like this:
On a system with a large number of storage devices connected, creation of management luns can result in an insufficient number of virtual
extension buses for the legacy representation of data luns. Since the number of extension buses on a system is limited to 256, luns
requiring virtual extension buses above 256 will be unusable through legacy device special files. Disabling the discovery and creation of
management luns will free up virtual extension buses for use by data luns.
Who Is Expected to Change This Tunable?
System administrators who expect to use a large number of storage devices requiring more than 256 extension buses through legacy device
special files.
Restrictions on Changing
Changes to this tunable take effect immediately. However, existing management luns will not be removed.
When Should the Tunable Be Turned On?
This tunable should be turned on when the system runs out of extension buses for configuring the legacy representation of data luns.
What Are the Side Effects of Turning the Tunable Off?
None.
When Should the Tunable Be Turned Off?
When the functionality provided by the management luns is desired.
What Are the Side Effects of Turning the Tunable On?
Existing management luns in the legacy representation will show up in the state.
What Other Tunables Should Be Changed at the Same Time?
None.
