A customer uses an S5600 storage system that contains one controller enclosure and five disk enclosures. During the deployment, after the controller enclosure is connected to five disk enclosures by using port EXP0, the OSM is logged in to from the IE browser. On the device panel, part of hard disks distributed in different enclosures are in the single-link state (the background color of these disks is yellow).
Only the disks that are in the normal physical state but identified by a single controller are displayed yellow in background color. These disks are in the single-link state.
An FC link supports a maximum of 127 nodes. For an S5000 storage system with 24 disk slots in an enclosure, an FC link supports a maximum of five enclosures. The link of port EXP0 includes the controller enclosure itself; therefore, port EXP0 supports a maximum of four disk enclosures. Port EXP1 supports a maximum of five disk enclosures.
