Is there a limit to the number of LUNS that can be concatenated using Solaris Volume manager with Soft partitions?
I have worked with some AIX admins in the past and there was such a limitation therefore limiting the size the filesystem could grow to.
Is there such a limitation in Solaris 9... (6 Replies)

What is the largest possible LUN size that can be presented to Solaris 10. I've been googling a lot about this. The new EFI lablels (an alternative to VTOC) supports LUNs greater than 2TB. I need to know the upper limit. please help me find it. (4 Replies)
Hi,
I need to set up iscsi LUN on Solaris 9. I've done it on Solaris 10 with iscsiadm. How do you do it on Solaris 9 though? Currently using Solaris 9 update 2. Your help is appreciated.
Thanks,

Hi All,
I'm using Solaris server, SunOS 5.10 Generic_144488-08 sun4u sparc SUNW, SPARC-Enterprise.
There is a newly created LUN of 250GB (EMC). I've scanned the system and able to see the new LUN.
For example:

Hello to all,
Actually, currently on my Solaris box, I've a LUN (5TB space) from a EMC storage which is working fine, and a partition with ZFS filesystem is created for that LUN. as further you'll see in the logs, the "c4t6006016053802E00E6A9196B6506E211d0s2" is the current configured LUN in the... (4 Replies)

fcd_disable_mgmt_lun(5) File Formats Manual fcd_disable_mgmt_lun(5)NAME
fcd_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.
The default value for this tunable is
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 lun 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.
