Hi,
I need to increase a veritas filesystem I have currently mounted on a Solaris 10 server. We can resize the LUN on the NetApp filer no problem. What I need to know is what do I do next on the Solaris 10 server I have so that it will see the increase in size. Do I run 'devfsadm' to... (3 Replies)
I had a pool which was exported and due to some issues on my SAN i was never able to import it again. Can anyone tell me how can i destroy the exported pool to free up the LUN. I tried to create a new pool on the same pool but it gives me following error

Hi All,
I am trying to read zpool.cache file to find out pool information like pool name, devices it uses and all properties.
File seems to be in packed format.I am not sure how to unpack it.
But from opensolaris code base we can see that they have used libz for uncompromising this file, but... (0 Replies)
Hello,
It's been a while since I've done AIX..., but I'm planning
a new TSM on AIX disk-only backup solution.
I'm planning to make an AIX volume group out of 40 luns of 1 TB.
I'm planning to create one big file system on here.
The purpose for this is to use this as a device class FILE for... (5 Replies)

Hello,
Does anyone know how I can tell what disk are being not being used by a zpool?
For example in Veritas Volume manager, I can run a "vxdisk list" and disks that are marked as "online invalid" are disk that are not used.
I'm looking for a similar command in ZFS which will easily show... (5 Replies)
Hi,
I am trying to setup multipathing (using DM multipath) for a redhat cluster setup ...all setup is done but issue is :

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.
