Solution software kit Host bus adapters FC interconnect hardware Coexistence with other multipathing products Secure Path 2. 0D Service Pack 3 for IBM AIX functions in a storage area network (SAN) environment with other HP multipathing products, such as Secure Path for SUN Solaris, Secure Path for Windows®, Secure Path for HP-UX, and Secure Path for XP and VA, as defined and described in the HP StorageWorks SAN design reference guide, which can be downloaded from this HP web site: http://h18006. www1. hp. com/products/storageworks/san/documentation. html Secure Path operational features Hardware prerequisites for Secure Path Two paths must exist between each server and storage system. [. . . ] Secure Path for IBM AIX does not tolerate this condition. You must stop all operations to an EVA storage unit prior to upgrading the HSVx software. Managing Secure Path 2. 0D Service Pack 3 for IBM AIX using smit Secure Path management tools have been integrated into the IBM AIX smit utility. From the smit menus, many different functions can be performed, such as: · Monitoring failover · Configuring failback · Resolving failures Most, but not all, of these functions may also be accessed by the Secure Path management utility (cbxfcsm). See the HP StorageWorks Secure Path 2. 0D for IBM AIX installation guide for more information about cbxfcsm. Secure Path 2. 0D Service Pack 3 for IBM AIX release notes 7 NOTE: If at any point, you want to see the command line smit uses to execute a function, press F6. From the smit utility System Management menu, select Devices>Cambex Fibre Channel Adapter. The following screen appears: Cambex Fibre Channel Adapter Move cursor to desired item and press Enter. You can add units to the currently active storage system. You can also add or remove a RAID storage system with one or more units defined. Adding and removing storage units See the HP StorageWorks Secure Path 2. 0D for IBM AIX installation guide for instructions about adding or removing storage units. Secure Path 2. 0D Service Pack 3 for IBM AIX release notes 9 Understanding hdisk-to-LUN assignments The IBM AIX cfgmgr command configures storage units, making them available for use. The hdisks assigned to the HSG80 RAID array are in sequence with the defined LUNs. This sequence can be interrupted by other devices that were defined previously by the IBM AIX system software. For example, hdisk4 through hdisk8 can be assigned to LUNs D1 through D5, hdisk9 can be another SCSI device, and hdisk10 through hdisk16 can be assigned to LUNs D6 through D12. LUNs are not required to be created sequentially. For example, you can create LUNs D1, D4, D6, and D12. The first hdisk is assigned to the first LUN, (in this case, hdisk4 to LUN D1), and the other assignments will follow sequentially (hdisk5 to D4, hdisk6 to D6, and hdisk7 to D12). If another LUN, D3, is added after the previously defined LUNs are configured, the sequence mapping is disrupted and hdisk8 is assigned to D3. Listing the hdisks List the hdisks by entering the # lsdev ­Cc disk command. In this example, hdisk5 shows a series of numbers 2D-08-00-0, 1. The first two numbers, 2D-08 are associated with the HBA. The last 2 numbers, 0, 1 are the target LUN designations. # lsdev -Cc disk hdisk0 Available 10-60-00-8, 0 16 Bit SCSI Disk Drive hdisk1 Available 30-78-00-1, 0 Other SCSI Disk Drive hdisk5 Available 2D-08-00-0, 1 Other SCSI Disk Drive Show units List the units created on the RAID storage system by entering the CLI SHOW UNITS command. This requires a serial connection to the HSG80 storage system. HSG_CONTROL> SHOW UNITS LUN Uses Used by --------------------------------------------------------------D1 DISK10000 D2 DISK20000 D4 DISK30000 D5 DISK30100 D6 DISK50300 D7 DISK30300 D8 DISK40100 Show association List the association of hdisks to RAID storage units using the Secure Path utility, /usr/cbxfc/cbxfcsm listall. In the following example, scsi2 and scsi3 are the HBAs for Secure Path. The first number (0) is the target designation and the second number is the LUN. # /usr/cbxfc/cbxfcsm listall # Device Online hdisk4 scsi3 0, 0 hdisk5 scsi3 0, 1 hdisk6 scsi3 0, 2 hdisk7 scsi3 0, 4 hdisk8 scsi3 0, 5 hdisk9 scsi3 0, 7 hdisk10 scsi3 0, 8 hdisk11 scsi3 0, 10 hdisk12 scsi3 0, 6 Alternate scsi2 0, 0 scsi2 0, 1 scsi2 0, 2 scsi2 0, 4 scsi2 0, 5 scsi2 0, 7 scsi2 0, 8 scsi2 0, 10 scsi2 0, 6 10 In the previous example, the hdisk4 assignment to LUN 0 is the Console LUN. The Console LUN is always enabled and assigned LUN 0 when in SCSI-3 mode. [. . . ] An attempt to remove both the hdisks and the HBAs simultaneously using rmdev -Rdl scsix may cause a system freeze, forcing a reboot. Paths to a RAID storage unit EVA requires that at least one port from each controller be connected into each fabric. Secure Path 2. 0D Service Pack 3 for IBM AIX requires that at least one path per HBA exists from the server to a LUN on the RAID storage system. Secure Path 2. 0D Service Pack 3 for IBM AIX release notes 11 Viewing LUNs after running cfgmgr If you enter the cfgmgr command, and can see the HBAs but not the LUNs, set the DMA size to 64 MB by entering the following commands: # rmdev -l scsi4 scsi4 Defined # chdev -l scsi4 -a dma_window=64M scsi4 changed # mkdev -l scsi4 Performance on Secure Path systems Avoid using multiple HBAs on the third PCI bus (pci2). Using pci2 on Secure Path systems has an adverse effect on system performance. Logging errors and debugging problems HP customer service representatives use the following commands to troubleshoot problems. Command # errpt -a # errpt -a > /tmp/ errorlog. txt # /usr/lpp/cbxfc/ runtrace # trcstop # trcrpt > /tmp/ trace. out Description Prints a full output of errors logged by the system. [. . . ]
