Hi,
How do I mirror an external scsi vg to one hdisk san? The vg has multiple hdisks and the san hdisk has only one.
Is this possible or do I need to create the same hdisks as the scsi? What I meant is, if the scsi vg has 10 hdisk then I need to create also 10 hdisk of san with the same... (6 Replies)

To summarize the problem: The "IBM FastT Storage Manager Client v8" shows that our Disk Farm is arranged into 6 logical drives each in a RAID 5 configuration. This software also shows that 5 of the 6 logical drives (from Disk Farm) are in a error state: "Failed Logical Drive - Drive Failure".... (1 Reply)

hi guys
I installed Centos 5.5 (local disk). I am using 2 HBAs
Now I mapped 5 LUNs from a Storage.
I will be using LVM
just to test I assigned a LUN I've read I have to use multipath to avoid my Centos see the LUN twice
I enabled mdmpd and multipathd...
something else I should do?

Has anyone tried SAN to SAN mirroring on IBM DS SAN Storage.
DS5020 mentions Enhanced Remote Mirror to multi-LUN applications
I wonder if Oracle High availibility can be setup using Remote Mirror option of SAN ? (1 Reply)

NAME
fp - Sun Fibre Channel port driver
DESCRIPTION
The fp driver is a Sun fibre channel nexus driver that enables fibre channel topology discovery, device discovery, fibre channel adapter
port management and other capabilities through well-defined fibre channel adapter driver interfaces.
The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
vate loop topologies, the driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
LIRP and LILP stages of loop initialization.
CONFIGURATION
The fp driver is configured by defining properties in the fp.conf file. The fp driver supports the following properties:
mpxio-disable
Solaris I/O multipathing is enabled or disabled on fibre channel devices with the mpxio-disable property. Specifying mpxio-disable="no"
activates I/O multipathing, while mpxio-disable="yes" disables the feature.
Solaris I/O multipathing may be enabled or disabled on a per port basis. Per port settings override the global setting for the specified
ports. The following example shows how to disable multipathing on port 0 whose parent is /pci@8,600000/SUNW,qlc@4:
name="fp" parent="/pci@8,600000/SUNW,qlc@4" port=0
mpxio-disable="yes";
manual_configuration_only
Automatic configuration of SCSI devices in the fabric is enabled by default and thus allows all devices discovered in the SAN zone to be
enumerated in the kernel's device tree automatically. The manual_configuration_only property may be configured to disable the default
behavior and force the manual configuration of the devices in the SAN. Specifying manual_configuration_only=1 disables the automatic con-
figuration of devices.
