Chapter 5: Designing the SAN 129 With an alias, you can rename the addresses of each server HBA to something that makes more sense to you — and do the same to the storage ports they’re assigned to in the switch. Instead of using the WWNs of the HBAs for mail server 1 in the zones, you can actually call it Mail_1A. The other HBA can be called Mail_1B. The different zones can be called Oracle and Mail. (Feel the headaches receding already? Good.) The Brocade switch commands used to create the zone information in Figure 5-33 would be as follows: admin> cfgCreate “Production”, “Mail_Zone; Oracle_Zone” admin> zoneCreate “Mail_Zone”, “Mail1A; Mail2A; Mail1B; Mail2B; Mail_disk” admin> zoneCreate “Oracle_Zone”, “Oracle1A; Oracle2A; Oracle1B; Oracle2B; Oracle_Disk” Server Mail1 20000000C8328FB6 20000000C8328FE7 The Active Zone Config="Production" that contains Zones: Mail Zone Oracle Zone Server Mail2 20000000C7328B74 20000000C7328B75 Mail Zone: Mail1A Mail1B Mail2A Mail2B Mail_Disk Oracle Zone: Oracle1A Oracle1B Oracle2A Oracle2B Oracle_Disk Server Oracle1 20000000C8327D97 20000000C8327D98 20000000C8328FB6 20000000C7328B74 20000000C8327D98 20000000C8327D97 20000000C7328B75 20000000C8328FE7 Figure 5-33: Sample zone alias naming. 20000000C8328AE7 50000000B2358D35 20000000C8328AE8 50000000B2358D34 20000000C8328AE7 20000000C8328AE8 Server Mail1 Switch 1 Inter-switch link Switch 2 (ISL) Name server database 20000000C8328FE6 alias "MailA" 20000000C8328FE7 alias "MailB" 20000000C7328B74 alias "Mail2A" 20000000C7328B75 alias "Mail2B" 20000000C8327D97 alias "Oracle1A" 20000000C8327D98 alias "Oracle1B" 20000000C8328AE7 alias "Oracle2A" 20000000C8328AE8 alias "Oracle2B" 50000000B2358D34 alias "Oracle_Disk" 50000000B2358D35 alias "Mail_Disk" Storage 50000000B2358D34 50000000B2358D35
