Windows - Disk Management console, Diskmgmt.msc

HP-UX

Rescan the devices:

# /usr/sbin/ioscan -C disk

ioscan – scan the I/O system

SYNOPSIS:

driver | class] instance] hw_path] | [devfile]

instance]

driver | class] instance] hw_path] [devfile]

driver | class] instance] lun hw_path] [devfile]

[devfile]

hw_path]

Generate device files: insf –e

Verify the new devices:   ioscan funC

AIX

Rescan the devices: cfgmgr vl fcsx, x is FC adapter number

Verify the new devices:   lsdev Cc

Linux

echo scsi add-single-device > /proc/scsi/scsi

Solaris

Determine the FC channels: cfgadm -al

Force rescan: cfgadm o force_update c configure cx

Where x is the FC channel number

Force rescan at HBA port level: luxadm e forcelip /dev/fc/fpx

Force rescan on all FC devices: cfgadm al o show_FCP_dev

Install device files: devfsadm

Display all ports:  luxadm e port

Display HBA port information luxadm -v display

Display HBA port information: luxadm e dump_map

To force Fibre Channel SAN disk rescan, Use device path from luxadm -e port output.

# luxadm -e forcelip

ESX/ESXi

Sign in to VMware Infrastructure Client. Select the ESX host and then click the “Configuration” tab. Select “Storage Adapters” from under Hardware. Click “Rescan”
