[. . . ] Depending on whether the logical units to be deleted are formatted or not, the message description is different. The logical unit information in which the logical unit has been deleted is updated and a window is displayed. ­ When no formatted logical unit exists: Acer | HDS WMS100TM User and Reference Guide 123 ­ When a formatted logical unit exists: 124 Chapter 7 Configuring Storage on the Thunder 9530TM V Series Subsystem 7. 3. 7 Formatting a Logical Unit Note 1: For the logical unit that is being formatted in the background, it is best to perform operations to the host installation. If a volatile failure for data in cache memory occurs due to subsystem power-off during formatting, the logical unit will be unformatted and data can be lost. Therefore, host installation operation should be performed from the first step for the logical unit. Note 2: When logical units are formatted, the user data will be initialized and completely deleted. Note 3: RAID group allocated to NAS system LU used and user LU at the time of NAS connection cannot be deleted without releasing the allocation. Note 4: Formatting will impact the host access performance, especially on the logical unit being formatted and on the logical unit in the same RAID group as the logical unit being formatted. Execute formatting during off-hours with less host access. When formatting the logical unit in the same RAID group as NAS system LU, do not boot or reboot the NAS OS. This could result in boot failure or increase in boot time of NAS OS. Format This mode enables the subsystem to start its operation earlier by formatting the specified LU in the background to make it usable by a host. Up to 512 LUs can be specified for formatting. This number can also be increased; however, the number of LUs that can be simultaneously formatted in the background is six per CTL. When executing formatting, the Storage Navigator Modular program can perform operations (such as a RAID group creation) while the formatting is being executed. When the Storage Navigator Modular program is terminated while formatting is executed, the formatting function is continued. When the Storage Navigator Modular program is terminated while formatting is executed, the formatting progress is displayed by percentage in the logical unit status column when the Storage Navigator Modular program is activated again. When the host I/O is executed for the LU in formatting, Format completion may be delayed; from the 99 % progress status, it may take 400 seconds (maximum). To format a logical unit, follow these steps: 1. Click the icon of a logical unit in the Unit window. On the Settings menu, select Logical Unit, and then click Format. Note 1 When you select multiple logical units, hold down the Ctrl key and click the icons of the logical units to format. [. . . ] When the received frame is the PLOGI, ADISC, or PDISC, a response is made with the LS_RJT. When the other frame is received, no response is made (the frame is abandoned). 282 Appendix D Interfaces D. 2 D. 2. 1 Ethernet Connection Specifications System Configuration To configure this NAS system, use the switches complied with the following standards: IEEE 802. 1D STP IEEE 802. 1w RSTP IEEE 802. 3 CSMA/CD IEEE 802. 3u Fast Ethernet IEEE 802. 3z 1000BaseX IEEE 802. 1Q Virtual LANs IEEE 802. 3ad Dynamic LACP RFC 768 UDP RFC 783 TFTP RFC 791 IP RFC 793 TCP RFC 1157 SNMP v1 RFC 1213 MIB II RFC 1757 RMON RFC 1901 SNMP v2 Acer | HDS WMS100TM User and Reference Guide 283 Cable The following table lists and describes the cable specification for LAN interface and the connector type.
