Dear Geek,
Have a good day.
DAEXXX is used as an example. For 5300 V3, 5500 V3, 5600 V3, and 5800 V3, DAE indicates the disk enclosure, the first X indicates the cabinet ID, the second X indicates the loop ID, and the third X indicates the expansion depth (that is, location of the connected disk enclosure in the loop).
For example, DAE000 indicates the disk enclosure that resides in location 0 of loop 0 in cabinet 0.
For 6800 V3 and 6900 V3, DAE indicates the disk enclosure, the first X indicates the engine ID, the second X indicates the loop ID, and the third X needs to be converted to binary. Specifically, the third X consists of four binary bits. The most significant bit indicates the loop ID, and the least three significant bits indicate the expansion depth (if the most significant bit is 0, the loop ID is equal to the value of the second X; if the most significant bit is 1, the loop ID is equal to 16 plus the value of the second X).
For example, DAE000 indicates the disk enclosure that resides in location 0 of loop 0 in cabinet 0.
DAE008 indicates the disk enclosure that resides in location 0 of loop 16 in cabinet 0.
DAE009 indicates the disk enclosure that resides in location 1 of loop 16 in cabinet 0.
In the preceding rules, the loop ID and expansion depth refer to the link information about expansion module A.
Note:
If the disk enclosure ID is displayed as DAE999, the enclosure ID is invalid. This may occur in either of the following conditions:
1. The disk enclosure is connected to the system for the first time by one link, and only the links to expansion module B are up.
2. The disk enclosure is connected by one link while its network is being adjusted, and only the links to expansion module B are up.
The disk enclosure ID will be displayed correctly after the disk enclosure has recovered from the single link fault.
Thanks.
