If the new hard disk is already recognized by IWSVA, skip the first step and go to step 2. You can confirm it using the following command:
# ls /dev/sd*
-
Add a new hard disk on IWSVA VM. If it is the second disk, its name would be /dev/sdb. For the third disk, it would be /dev/sdc.
-
Use the command to list all available partitions:
# ls /dev/sd*
-
Determine which SCSI host is in use:
# grep mpt /sys/class/scsi_host/host?/proc_name
The command will return a line such as "/sys/class/scsi_host/host0/proc_name:mptspi". In this example, the SCSI host is "host0".
-
Then rescan the bus by informing the SCSI host that has been determined in the previous step. The 3 “-” are acting as wildcards to represent the “Channel, SCSI ID and LUN” that are available on a SCSI host.
# echo "- - -" > /sys/class/scsi_host/host0/scan
-
Repeat the command to list all available partitions and note that the new disc is now listed. In this example, the new disk is /dev/sdb.
# ls /dev/sd*
-
-
Create a partition and change its type to Linux Logical Volume Manager (LVM):
# fdisk /dev/sdb
• Type n = add new partition
• Type p = primary
• Type 1 = only one partition
• Press Enter to use the Default First cylinder
• Press Enter to use the Default Last cylinder
• Type w = Save the changes -
List all available partitions and note that the new partition is now listed. In this case the new partition is /dev/sdb1:
# ls /dev/sd*
-
Run the command "mke2fs -j /dev/sdb1" to format /dev/sdb1.
# mke2fs -j /dev/sdb1
Make sure to type the right partition. Otherwise, this command will format the incorrect partition and damage the IWSVA installation. -
On the IWSVA WebUI, go to Logs > Log Settings. On the Mount device field, enter the new "/var/offload" device /dev/sdb1 then click Mount.
The purge days must be more than 45.On the Store logs for field, enter "45". Select the Log Offload checkbox then click Save.
