Using the Emulex lun_scan script

Installing and Configuring the Linux Host with the Emulex Driver

2. If the system contained multiple Emulex HBAs, the command

could be run with specific SCSI host numbers.

For example, this system has four Emulex HBAs:

[root@l82bi183 /]# ls /proc/scsi/lpfc/

2 3 4 5

To rescan the SCSI bus for LUNs on some of the HBAs, the SCSI

host numbers for those HBAs may be specified:

[root@l82bi250 /]# lun_scan 2 5

Scanning lpfc2, scsi host number : 2

Scanning lpfc5, scsi host number : 5

3. To rescan the LUNs on all of the Emulex HBAs within the system,

execute the following:

[root@l82bi183 /]# lun_scan all

Scanning lpfc2, scsi host number : 2

Scanning lpfc3, scsi host number : 3

Scanning lpfc4, scsi host number : 4

Scanning lpfc5, scsi host number : 5

1 2 ... 90 91 92 93 94 95 96 97 98 99 100 ... 181 182
