[. . . ] · Prohibit Dynamic Connectivity Mask (PDCM) values are read from the IPL; the default is Allow All. · HP Advanced Zoning, if used, continues to be in force. If there are any differences in restrictions set up with HP Advanced Zoning and PDCM, the most restrictive rules are applied. · RSCNs are sent to devices if PDCM results in changes to connectivity between a set of ports. Changing fmsmode from enabled to disabled triggers the following events: · A device reset is performed on the control device. · RSCNs might be generated to some devices if PDCM removal results in changes to connectivity between a set of ports. · If a given port was set to Block or Unblock, that port remains disabled or enabled. · Serialized access to switch parameters ceases. Setting up CUP when FMS mode is enabled Fmsmode may be enabled and in use on a switch without a CUP License. The transition from fmsmode disabled to fmsmode enabled with the CUP license installed triggers the notification to the host systems that the CUP feature is available. Without this notification, the host systems never know the CUP feature is available, and consequently never try to communicate with it. Hence, it is possible that fmsmode may already be enabled on the switch. If FMS mode is already enabled, set up CUP as follows: 1. Verify that FMS mode is enabled by entering the ficoncupshow fmsmode command. If FMS mode is not enabled, see "Enabling and disabling FMS mode" on page 112. CAUTION: If fmsmode is already enabled, disabling it might be disruptive to operation, because ports that were previously prevented from communicating are now able to do so. If FMS mode is enabled, disable it by issuing the ficoncupset fmsmode disable command. Install a CUP license key as described in "Adding and removing FICON CUP licenses" on page 116. Issue the ficoncupset fmsmode enable command. Displaying the fmsmode setting The ficoncupshow fmsmode command displays the effective fmsmode setting for the switch. For example: switch:admin> ficoncupshow fmsmode fmsmode for the switch: Enabled Displaying mode register bit settings The mode register bits are described in Table 19. Fabric OS 5. x administrator guide 113 Table 19 Bit POSC UAM ASM FICON CUP mode register bits Description Programmed offline state control. When this bit is set on, the host is prevented from taking the switch offline. When this bit is set on, a warning is issued when an action is attempted that writes CUP parameters on the switch. When this bit is set on, all CUP configuration parameters are persistent, meaning that they are saved in nonvolatile storage in the IPL file that is applied upon a cold reboot or a power cycle. [. . . ] Start a new telnet session and use the firmwareDownloadStatus command to check the status. For example: switch: admin> firmwaredownload -s Server Name or IP Address: 192. 1. 2. 3 User Name: JohnDoe File Name: /pub/v5. 0. 1/release. plist Password: ***** Do Auto Commit after reboot [Y]: y Reboot system after download [N]: y Firmwaredownload has started. . Upgrading a single Core Switch 2/64 or SAN Director 2/128 blade Although it is possible to upgrade firmware on one CP blade at a time, not do so under normal circumstances, because it might disrupt switch operations if it is not executed in the proper sequence, or if the version of firmware is down-level and part of an unsupported version. When the two CP blades are not running the same firmware versions, it might be necessary to disable one or the other blades to maintain fabric stability. [. . . ]
