2 | For HACMP configurations in standby and mutual takeover mode: |
| v PCI |
| The two adapters must not be in the same using system. |
| v PCI |
| The two adapters must not be in the same using system. |
| The adapters must be in two separate using systems. |
| For |
| systems or to the same using system, but disk drive modules must not be shared: |
| v PCI |
| v PCI |
| v Ultra2 SCSI Integrated port |
Attention: This 2104 configuration is not supported on the Linux operating system. | |
| Attention: The SCSI address of the adapter that is connected to the 2104 must be |
| different from the addresses of the installed disk drive modules. When a second |
| adapter is connected to a 2104, the SCSI address of that adapter must be different |
| from the address of the first adapter and the addresses of the disk drive modules |
| installed in the 2104. |
| In each 2104, slots 6 and 7 (SCSI addresses 5 and 6) must contain dummy disk |
| drive modules. Each 2104 can contain no more than 12 disk drive modules. |
