Hi
I have a linux box attched to a SAN storage from EMC with RAID 5 .I understand that it has 3g cache howver a 20gb file creation takes too much time here are my results any ideas why

I have my application vendor looking at this but I want to do my own investigation.
I restored from mksysb and I see my vgs that contain my internal disks.
But I do not see my vgs that contain disks from the SAN. This scares me ..

This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)

Hi,
I'm new to SAN storage so I was wondering if someone can assist me with a problem. I have a solaris 10 OS with 3 SAN devices attached. We are trying to troubleshoot performance so I was asked to get the WWN of each SAN disk and show what it's attached to via the SVM mount in the metastat... (1 Reply)
Hello everybody,
I'm using the binary inqraid (Linux RHEL) in order to retrieve information about SAN disks. The questions are:
Given an LDEV, how do I know if the SAN disk related to this LDEV is being used by the OS? I mean, how can I demonstrate to "Storage department" that all disks of... (4 Replies)

qlc(7D)qlc(7D)NAME
qlc - ISP2200, ISP2300, and SP212 Family Fibre Channel host bus adapter driver.
SYNOPSIS
SUNW,qlc
The qlc host bus adapter driver is a Sun Fibre Channel transport layer-compliant nexus driver for the Qlogic ISP2200, ISP2200A, ISP2310,
ISP2312, and SP212 adapters. These adapters support Fibre Channel SCSI and IP Protocols, FC-AL public loop profile, point-to-point fab-
ric connection and Fibre Channel service classes two and three (see NOTES section below).
The qlc driver interfaces with the Sun Fibre Channel transport layer to support the standard functions provided by the SCSA interface. It
supports auto request sense and tagged queueing by default. The driver requires that all devices have unique hard addresses in private
loop configurations. Devices with conflicting hard addresses are not accessible.

SP-212-based host bus adapters (including QLA-210) are supported on x86 platforms only and are limited to a maximum of 8 targets in fab-
ric and sixteen targets in local loop topology. FL topology is not supported with the SP-212-based host bus adapter.
