I have directly connected my IBM Pseries AIX machine to SAN Storage
I have a dual port Fibre Channel Adapter
Connected both fiber ports to SAN Box IBM DS4500 Controller A & Controller B
Using IBM DS storage manager client 10 -- created one logical disk and assigned to a default group
on my AIX machine
I see two disks in my AIX machine HDISK8 and HDISK9 is same disk but appearing twice . I have disconnected one cable from the controller , deleted hdisk9 and ran cfgmgr , I don't see hdisk9
Do I need to have SAN Switch inorder for it to appear only once or is there any other configuration which I am missing.... ?
Hi All,
I have mirrored SAN volume on my B80 rootvg. Can I just remove the mirror and "Remove a P V from a V G" and it will be a diskless AIX?
Is that going to boot on SAN rootvg volume?
Thanks in advance,

We are considering a DR strategy of booting AIX 5.3 and 5.3 logical partitions from EMC Symmetrix SAN disks, so that we can replicate via SRDF to a recovery site. Has anyone tried configuring AIX 5.x systems to boot from SAN disk? If so, can you provide any information on the pros and cons of... (6 Replies)

Scenario:
I've got 2 M5000's connected to a 9985 SAN storage array. I have configured the SAN disks with stmsboot, format and newfs. I can access the same SAN space from both systems. I have created files from both systems on the SAN space.
Question:
Why can't I see the file created... (3 Replies)
Hi all,
My main function is as a DBA. Another person manages the server and the SAN.
I just want to know if I should be worried about high disk I/O or is it irrelevant as the I/O "load balancing" will be "taken care" of by the SAN?
For example, I have hdisk1-5 and I can see that there are... (2 Replies)

I have a production solaris 10 SPARC system (portal). Yesterday legato/Networker gave an I/O Error on one of the files on its SAN mounted disk.
I went to that particular file on the system, did an ls and it showed the file. However, ls -l did not work and it said IO error.

raidctl
raidctl(1M) System Administration Commands raidctl(1M)NAME
raidctl - RAID hardware utility
SYNOPSIS
raidctl -c disk1 disk2
raidctl -d disk1
raidctl [-f] -F filename controller...
raidctl -l [controller...]
DESCRIPTION
The raidctl utility creates, deletes, or displays RAID volumes of the LSI1030 HW Raid controllers that include RAID support. The utility
also updates firmware/fcode/BIOS for both RAID and non-RAID controllers.
The raidctl utility requires privileges that are controlled by the underlying file-system permissions. Only privileged users can manipulate
the RAID system configuration. If a non-privileged user attempts to create or delete a RAID volume, the command fails with EPERM.
Without options, raidctl displays the current RAID configuration on all exisiting controllers.
OPTIONS
The following options are supported:
-c disk1 disk2 (for on board)
Create a mirror using disk1 and disk2. Replace the contents of disk2 with the contents of disk1. Specify disk1 and disk2 in canonical
form, for example, c0t0d0.
When you create a a RAID volume, the RAID volume assumes the identity of the first target in the disk pair (disk1). The second target
(disk2) disappears from the system. Therefore, the RAID volume appears as one disk.
To have a successful RAID creation, there must not already be a RAID configuration present on the specified controller. Additionally,
the secondary disk must not be mounted, as it has all its data erased and replaced with the primary disk's data.
-d disk1 (for on board)
Delete the RAID volume specified as disk1.
Specify disk1 in canonical form, for example, c0t0d0.
-f (for HBA)
Force an update. Do not prompt.
-F filename controller (for HBA)
Update the firmware running on the specified controller (controller).
-l [controller ...] (for on board)
List the system's RAID configuration. If controller is specified, list RAID configurations for controller.
Output from the -l lists the following information:
RAID Volume Displays logical RAID volume name.
RAID Status Displays RAID status as either RESYNCING (disks are syncing), DEGRADED RAID is operating with reduced functionality),
OK (operating optimally), or FAILED (non-functional).
RAID Disk Displays RAID disk name.
Disk Status Displays disk status as either OK or FAILED.
EXAMPLES
Example 1: Creating the RAID Configuration
The following command creates the RAID configuration:
# raidctl -c c0t0d0 c0t1d0
RAID Volume 'c0t0d0' created
Example 2: Displaying the RAID Configuration
The following command displays the RAID configuration:
# raidctl
RAID RAID RAID Disk
Volume Status Disk Status
----------------------------------------
c0t0d0 RESYNCING c0t0d0 OK
c0t1d0 OK
Example 3: Deleting the RAID Configuration
The following command deletes the RAID configuration:
# raidctl -d c0t0d0
RAID Volume 'c0t0d0' deleted
Example 4: Updating Flash Images on the Controller
The following command updates flash images on the controller:
# raidctl -F lsi1030.fw 0
Update flash image on controller 0? (y/N): y
Flash updated successfully
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 Invalid command line input.
2 Request operation failed.
