Check the HBA (fcinfo Command) If the older version of the HBA is installed, the output looks like this: # fcinfo hba-port HBA Port WWN: 21000024ff56bce8 Port Mode: Initiator Port ID: 0 OS Device Name: /dev/cfg/c28 Manufacturer: QLogic Corp. Model: 371-4325-02. 2. Try to configure the new FC HBA: # cfgadm -c connect iou#0-pci#3 # cfgadm -c configure iou#0-pci#3--> did not work, same errors and Name_Property on XSCF did not change B) 0. Check there are no fma faults. If any clear fma fault as before. 1. Unconfigure and disconnect the FC HBA # cfgadm -c unconfigure iou#0-pci# Displaying Fibre Channel Devices. The commonly used commands for adding, removing, and displaying FC devices are as follows: fcinfo - Collects and displays administrative information about FC-HBA ports on hosts, remote ports, and configured logical units. For more information, see the fcinfo(1M) man page. The following examples show the most common administration operations that can be.
The CRC errors were continuosly increasing, so I knew that either the HBA or fibre channel cable were faulty (as a side note, I can't wait for the FMA project to harden the emlxs and qlc drivers!). During one of my storage training courses, the instructor mentioned that CRC errors are typically associated with bad cables Similar to a network card having a unique MAC address, every HBA port will have a unique WWN number. Solaris 10 and Solaris 11. We can get a list of HBA ports using the luxadm command. Remember that luxadm command only work on hba's that are bound to the Oracle drivers. So if native (non oracle) Emulex driver is in use then the luxadm command.
One the most useful new command I found in Solaris 10 is fcinfo, a command line interface that will display information on HBA ports on a host, but also many useful bits of information on connected storage remote port WWN, raid type, link status,etc. root # fcinfo hba-port -l HBA Port WWN: 10000000c957d408 ==> How do I to check and measure FC HBA utilization? How do I determine how much io is going through an HBA? How do I determine if an HBA is being overloaded with io? How do I determine if an HBA has reached its available capacity limit? We want to monitor the data transfer/sec with each Fibre Channel Adapte
The best way to test for a healthy HBA is to use the vendor utilities or, if you have Sun's Leadville drivers installed, using the SAN Tools (cfgadm I believe). Also, you can tail the /var/adm/messages file and watch the errors from any activity to a down path. Hope that helps cfgadm and fcinfo commands can be used to list all the LUNs presented to a HBA or a disk controller in Oracle Sun Solaris 10 Sun Solaris System Admin Sun Solaris HowTo's Tips Tricks Tutorial
. Using fcinfo (Solaris 10 only) This is probably the easiest way to find the WWN numbers on your HBA card. Here you can see the HBA Port WWN (WWpN) and the Node WWN (WWnN) of the two ports on the installed Qlogic HAB card Run the iostat command without any arguments to see the complete statistics of the system. # iostat Linux 4.19.32-1-MANJARO (daygeek-Y700) Thursday 18 April 2019 _x86_64_ (8 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 29.45 0.02 16.47 0.12 0.00 53.94 Device tps kB_read/s kB_wrtn/s kB_dscd/s kB_read kB_wrtn kB_dscd nvme0n1 6.68 126.95 124.97 0.00 58420014 57507206 0 sda 0.18 6.77 80.

Hello, In Solaris 10 I can use fcinfo to find what speed the hba ports are running at, am I able to find this out using Solaris 9? I have tried a few variations on luxadm but cant find anything relevant. Thanks
Then the Linux developers started to standardize the FC driver interface a bit. In RHEL 5, the work is still on-going, but you can expect to find the HBA information in two places: - the FC-specific information should be available in virtual files at /sys/class/fc_host/host*/ directories (one for each FC port) 1) From a Solaris server, I run the command iostat -En and receive output that is similiar to the following which shows your disks along with the cdrom/dvdrom: c0t2d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Model: Maxtor 6E040L0 Revision: NAR61590 Serial No: E1FECWNE Size: 41.11GB <41110142976 bytes> Media Error: 0 Device Not Ready: 0.

After investigating, they have confirmed there is No problem from SAN storage end and they said the CRC errors are generated only from a particular Emulex HBA card (out of 2). They gave couple of recommendations to stop the CRC errors: 1. To check the Physical connectivity of Fabric connectivity between ESXi host and Fabric switch 2. An internal circuit on one of the drives has gone bad, resulting in the drive not being able to sendor receive FC frames correctly. In this situation, the drive receives data that does not match the parity bit
Introduction. The fsck (File System Consistency Check) Linux utility checks filesystems for errors or outstanding issues.The tool is used to fix potential errors and generate reports. This utility comes by default with Linux distributions. No specific steps or an installation procedure is required to use fsck In Today's high speed systems PCI Express (PCIe-Peripheral Component Interconnect-express) has become the backbone. PCIe is a third generation high performance I/O bus used to interconnect peripheral devices in applications such as computing and communication platforms. It is used to provide the.

This article is intended as a brief introduction to some of the commands in Solaris that will help you achieve your tasks. Firstly, in order to allow your storage admin to map you some LUNs, you'll need to provide him with the WWNs of the HBA ports in your server. This is so he can map the LUNs you've asked for to the WWNs of your server If your server has two HBA cards connected to EMC SAN storage device, you can implement load-balancing, and fail-over on the HBA cards using the EMC PowerPath software.. Powermt management utility helps you manage I/O paths from the server to the EMC storage device. In this article, let us discuss how to use powermt command with practical examples vHBA provides multiple benefits: Device functionality: - Solaris in the domain uses native device drivers, and can use full functionality for SCSI reserveration and MPxIO for path management Device generality: - Any device Solaris supports on a physical HBA is supported in the virtual HBA. For example, the guest domain will be able to use tape devices for backup This script has exported HBA and VNICs firmware and driver versions info for all of my HPE ESXI hosts. If you want specific cluster or specific host, change the first line of the script with one of the following
UNIX commands, such as snapdrive storage create and snapdrive config prepare luns: 0001-876 Admin error: HBA assistant not found You must verify that the required number of paths are up and running Note (Oracle Solaris 11.4): Please note that there are several Oracle Solaris EOFs which could affect platform support using Oracle Solaris 11.4. We are in the process of identifying those that are fully supported, and recommend testing of existing hardware systems and components before putting them into a production environment with Oracle Solaris 11.4 The HBA Model will be listed as QLExxxx.

and check the log file for errors (that is important, as a syntactically wrong file won't be loaded). The alternative is to enable SSL on the server side and use it for the local connection. The fastest way to connect would be via Unix sockets (if you are not on Windows or use the JDBC driver), perhaps that is the best thing to do You should now understand how to use df and du commands to check disk space on your Linux system. Remember, to display a complete list of options, use either df --help or du --help . Check out our article on how to use fsck command to run a filesystem check as preventive maintenance or when there is an issue with your system Now we need to map the device 'vfchost2' to the physical HBA port 'fcs1' using the 'vfcmap -vadapter vfchost2 -fcp fcs1'command.Once it is mapped, check the status of the mapping using the command 'lsmap -vadapter vfchost2 -npiv'.Please note that the status of the port is showing as 'NOT_LOGGED_IN', this is because the client configuration is not yet complete and hence it.

Matching driver and firmware phase seems indeed to be more of a thing under FreeNAS, in my experience things just work on Linux. Regarding mpt2sas vs mpt3sas, IIRC one had been forked off the other - memory's fuzzy there, but I think one came with the Linux kernel, the other was from LSI Established in 2010, a community for system admins and developers.

AGAIN, check those things, and work with your SAN team to figure it out. There is no magic command you can run to make a device appear. Since all your other devices are appearing, it's time to actually start looking at the system, involving the SAN team, the SAN vendor, and your Solaris support vendor lsscsican be used to check whether the SCSI devices are seen correctly by the OS. When the LUNs are not seen by the HBA driver, check the zoning setup of the SAN. In particular, check whether LUN masking is active and whether the LUNs are correctly assigned to the server. LUNs are seen by the driver, but there are no corresponding block device Client authentication is controlled by a configuration file, which traditionally is named pg_hba.conf and is stored in the database cluster's data directory. (HBA stands for host-based authentication.)A default pg_hba.conf file is installed when the data directory is initialized by initdb.It is possible to place the authentication configuration file elsewhere, however; see the hba_file.
