With the introduction of Solaris 10, storage management has changed considerably. The storage foundation kit is now integrated into the base OS, the leadville driver has been expanded to include HBAs from Emulex, JNI and Qlogic, and the fcinfo utility as well as several mdb DCMDS were added to view fibre channel connectivity information. fcinfo is especially useful, since it provides a tool with the base Operating System to view HBA and connectivity information.
The fcinfo utility has two main options. The first option, “hba-port,” will display HBA port speeds, WWPNs, the HBA manufacturer, and the state of the HBA:
$ fcinfo hba-port
HBA Port WWN: 10000000c9327592 OS Device Name: /dev/cfg/c2 Manufacturer: Emulex Model: LP9002L Type: N-port State: online Supported Speeds: 1Gb 2Gb Current Speed: 2Gb Node WWN: 20000000c9327592
HBA Port WWN: 10000000c9327593 OS Device Name: /dev/cfg/c3 Manufacturer: Emulex Model: LP9002L Type: N-port State: online Supported Speeds: 1Gb 2Gb Current Speed: 2Gb Node WWN: 20000000c9327593
If the “-l” option is specified, fcinfo will also print link statistics (e.g., link failure, signal loss, etc.):
$ fcinfo hba-port -l
HBA Port WWN: 10000000c9327592 OS Device Name: /dev/cfg/c2 Manufacturer: Emulex Model: LP9002L Type: N-port State: online Supported Speeds: 1Gb 2Gb Current Speed: 2Gb Node WWN: 20000000c9327592 Link Error Statistics: Link Failure Count: 0 Loss of Sync Count: 5 Loss of Signal Count: 0 Primitive Seq Protocol Error Count: 0 Invalid Tx Word Count: 0 Invalid CRC Count: 0
HBA Port WWN: 10000000c9327593 OS Device Name: /dev/cfg/c3 Manufacturer: Emulex Model: LP9002L Type: N-port State: online Supported Speeds: 1Gb 2Gb Current Speed: 2Gb Node WWN: 20000000c9327593 Link Error Statistics: Link Failure Count: 0 Loss of Sync Count: 5 Loss of Signal Count: 0 Primitive Seq Protocol Error Count: 0 Invalid Tx Word Count: 0 Invalid CRC Count: 0
The second fcinfo option is “remote-port,” which will display information on remote targets. This information includes the storage manufacturer, the storage product type, WWPNs, and all of the SCSI targets that have been presented to the host:
$ fcinfo remote-port -slp 10000000c9327592
Remote Port WWN: 50060160082006e2 Active FC4 Types: SCSI SCSI Target: yes Node WWN: 50060160882006e2 Link Error Statistics: Link Failure Count: 0 Loss of Sync Count: 0 Loss of Signal Count: 0 Primitive Seq Protocol Error Count: 0 Invalid Tx Word Count: 255 Invalid CRC Count: 0 LUN: 0 Vendor: DGC Product: RAID 5 OS Device Name: /dev/rdsk/c4t6006016061B71000AD0810C9979CD911d0s2 LUN: 1 Vendor: DGC Product: RAID 5 OS Device Name: /dev/rdsk/c4t6006016061B7100055B12704989CD911d0s2 Remote Port WWN: 50060168082006e2 Active FC4 Types: SCSI SCSI Target: yes Node WWN: 50060160882006e2 Link Error Statistics: Link Failure Count: 0 Loss of Sync Count: 0 Loss of Signal Count: 0 Primitive Seq Protocol Error Count: 0 Invalid Tx Word Count: 255 Invalid CRC Count: 0 LUN: 0 Vendor: DGC Product: RAID 5 OS Device Name: /dev/rdsk/c4t6006016061B71000AD0810C9979CD911d0s2 LUN: 1 Vendor: DGC Product: RAID 5 OS Device Name: /dev/rdsk/c4t6006016061B7100055B12704989CD911d0s2
These changes should make managing storage on Solaris a bit easier.
