24 Best Practices for Sharing an iSCSI SAN Infrastructure with Dell PS Series and SC Series Storage using VMware vSphere
Hosts | 2015-A-BP-INF
5.2.2 VMware native multipathing
VMware provides native multipathing that can be used with any storage platform, if a vendor-provided
multipath solution is not available.
5.2.3 Setting Path Selection Policy and storage performance settings - SC Series
VMware hosts connected to the SC Series storage platform must use VMware’s native multipathing for
SC Series volumes. Setting the Path Selection Policy (PSP) can be performed using either the vCenter GUI
or a command line utility. Setting the PSP Default, and performance aspects of the PSP can only be
performed using a command line utility at this time. Command line utility options are: ESXi console, SSH
session, vSphere CLI, or VMware PowerCLI. The SSH session commands are shown here:
Note: At the time of this writing, the local vSphere host GUI, the new web-based utility that has replaced the
C-Sharp client, does not have the ability to set PSP for volumes.
To set Path Selection Policy default for new SC Series (SCOS v6.6 and up) volumes:
[root@ESXi-BCM-PS:~] esxcli storage nmp satp set –P VMW_PSP_RR –s VMW_SATP_ALUA
To set or change the PSP for an existing SC Series volume:
[root@ESXi-BCM-PS:~] esxcli storage nmp device set --device=naa.xxx --psp=VMW_PSP_RR
To set the Round Robin IOPS policy for an existing SC Series volume:
[root@ESXi-BCM-PS:~] esxcli storage nmp psp roundrobin deviceconfig set --device=naa.xxx/
--type=iops --iops=3
Note: Additional details, scripting options, and instructions for previous versions of SCOS are provided in
