ACS Enhancements and Fixes Other Enhancements Host Connection Maximum and New Instance Code, 43036A64 If you exceed the maximum number of host connections (96), ACS now notifies you of the discrepancy. A new instance code, 43036A64, is issued, and if you attempt to add new connections after the maximum number of connections is reached, they are rejected.
ACS Enhancements and Fixes The addition of this new data provides additional troubleshooting guidance. See the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software Troubleshooting Guide for additional information. SHOW CONNECTIONS FULL command and additional screen display information After entering the SHOW CONNECTIONS FULL CLI command, connection details are now displayed at the bottom of the subsequent screen.
ACS Enhancements and Fixes ACS Downgrade With this release, you can downgrade ACS from V8.8-1 to V8.7-1 or V8.6-1 (the base version). No other versions are supported. With this, changes have been made to associated screens. Contact HP support for additional information. Note: If you are downgrading ACS V8.8-1 and pre-existing patches from V8.6 or V8.7 remain in controller memory, the system downgrades your system to the highest patch level that was previously installed.
ACS Enhancements and Fixes Note: Since other operating systems may not re-register their persistent reservation settings with the array controller based upon a single unit’s persistent reservation conflict, you must invoke the SET unit number FAKE_PR command if there are units with devices not mounted by Tru64 UNIX (that is, units mounted by another supported operating system).

ACS Feature Support ACS Feature Support The following sections provide details for specific ACS features. SCSI-2 to SCSI-3 Migration In order to extend interoperability within the heterogeneous SAN, HP highly recommends that customers begin migrating from SCSI-2 to SCSI-3 protocols. Moving to SCSI-3 allows greater diversity in the operating systems (OS) and storage products (including EVA) that comprise a SAN. All migrations from SCSI-2 to SCSI-3 should be planned during scheduled downtime.
Host Operating System Notes Host Operating System Notes The following section lists host-specific operating notes. Host Operating System Support of Multi-Bus Failover Multi-bus failover is supported on the Sun Solaris operating system through the use of Secure Path software. See “Secure Path Software” on page 35, for version compatibility and restrictions.
Host Operating System Notes Installation Script May Not Correctly Modify the /etc/nsswitch.conf File In NIS Configurations If you are using NIS, make sure that your services entry in /etc/nsswitch.conf looks like this: services: files nis This will ensure the edits made to the /etc/services file will be used. Maximum Supported Storageset Size With this release, Solaris can support storagesets up to 1.
Host Operating System Notes To change scsi_probe_delay values, the following configuration files (depending on bus architecture), found in the /kernel/drv directory, should be edited: 32-bit Sbus: fca.conf 64-bit Sbus: fcaw.conf 32-bit PCI Bus: fca-pci.conf Messages on Console After Driver Initializes You may see messages similar to the following on the console after the driver initializes: /kernel/drv/fca symbol ddi_model_convert_from multiply defined NOTICE: fca_transparent: utsname.release: 5.
Host Operating System Notes Number of Supported LUNs This release of HP Solution Software adds support for 16 LUNs per port/Target. This should be adequate for most installations. However, the array controller and Solaris can support up to 64 LUNs per port/Target. If your environment requires more than 16 LUNS/Target, you may perform the following work-around, keeping the following items in mind: ■ Make sure that all the required patches are loaded.
Host Operating System Notes you are doing heavy I/O to 16 or more LUNs, you need to set sd_max_throttle even lower. Edit your /etc/system file, and change the sd_max_throttle entry in the CPQfcraid section. You must shutdown and reboot for the changes to take effect. Set sd_max_throttle so that the number of active LUNs on the port times sd_max_throttle is less than or equal to 256 (the maximum number of queued requests for the port).
Host Operating System Notes To properly configure a storageset where the logical geometry exceeds these values, follow these steps: 1. Get the size of the storageset by performing a SHOW on the unit from the CLI on the array controller (e.g. SHOW D100).
Host Operating System Notes ■ 169 sectors per track 4. At this point, allocate the alternate cylinders (2) from the total number of cylinders to get the following values: ■ 24531 data cylinders ■ 2 alternate cylinders ■ 60 heads ■ 169 sectors per track Write down the above data and proceed with the next step. 5. Using the format utility, reconfigure your storageset's logical geometry. ■ From the main menu, select the storageset. ■ From the type menu, select other.
Host Operating System Notes Command Console LUN The array controller can provide a dedicated communications LUN called the Command Console LUN (CCL). The CCL can cause some issues under Solaris. During booting, you receive a corrupt label - bad magic number error because Solaris “sees” the CCL as a 320MB read-only disk. This message is just a warning and can be ignored. You may disable the CCL if desired.
ACS Anomalies ACS Anomalies If you issue the INITIALIZE SAVE_CONFIGURATION CLI command on a JBOD disk to save the controller configuration while the unit is not above the container, the command appears to work, but the save operation does not occur. You must place the unit above the JBOD, and then issue the INITIALIZE SAVE_CONFIGURATION to accomplish this task. 46 HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.
