Dell Technologies recommends installing Linux packages sg3_utils and lsscsi. These packages offer important tools for managing SCSI devices, as illustrated in this paper. To scan for non-NVMe PowerStore volumes, run the following command:
/usr/bin/rescan-scsi-bus.sh -a
To query the WWN on a Linux operating system, run the following commands against the device file.
Oracle Linux or Red Hat Enterprise Linux 6.x:
/sbin/scsi_id --page=0x83 --whitelisted --device=<device>
Oracle Linux or Red Hat Enterprise Linux 7.x and 8.x:
/usr/lib/udev/scsi_id --page=0x83 --whitelisted --device=<device>
If the system has Linux device-mapper-multipath software enabled, the multipath command displays the multipath device properties including the WWN. For example:
To view the WWN and LUN ID information in PowerStore Manager, follow these steps:
The WWN and Logical Unit Number (LUN ID) appear in the list of volumes that PowerStore Manager returns.
If columns WWN and Logical Unit Number are not displayed, use the field selector to add them to the displayed data.
