Abstract
This document outlines the recommended settings for EMC VMAX models supported with SAN Volume Controller , Storwize V7000, V5000 and FlashSystems V840 and V9000
Content
Please refer to this table when virtualizing VMAX Controllers with the above IBM Products.. Where other than recommended below the bit settings on VMAX should remain at factory default when virtualized behind SAN Volume Controller , Storwize V7000, V5000 and FlashSystems V840 and V9000
| Recommended Director Bit Settings for VMAX with SVC | ||||
| Director Bit SCSI Flags | VMAX 10K 20k 40K | VMAX3 SVC/Storwize 7.3 and higher 100K 200K 400K | Notes | |
| Negotiate_Reset(N) | Disabled | Disabled | ||
| Soft_Reset(S) | Disabled | Disabled | ||
| Environ_Set(E) | Disabled | Disabled | ||
| HP3000_Mode(B) | Disabled | Disabled | ||
| Common_Serial_Number(C) | Enabled | Enabled | ||
| Disable_Q_Reset_on_UA(D) | Disabled | Disabled | ||
| Sunapee(SCL) | Disabled | Disabled | ||
| Siemens(S) | Disabled | Disabled | ||
| Sequent(SEQ) | Disabled | Disabled | ||
| Avoid_Reset_Broadcast(ARB) | Disabled | Disabled | ||
| Server_On_AS400(A4S) | Disabled | Disabled | ||
| SCSI_3(SC3) | Enabled | Enabled | 1. Factory Default setting is not to be changed since EMC requires setting the SC3 and SPC2 flags. 2. SC3 and SPC2 are advertised and is non-configurable. | |
| SPC2_Protocol_Version(SPC2) | Enabled | Enabled | 1. Factory Default setting is not to be changed since EMC requires setting the SC3 and SPC2 flags. 2. SC3 and SPC2 are advertised and is non-configurable. Customers running SAN Volume Controller or Storwize versions earlier than 7.1 the SPC-2 bit should be set to "Disabled". For customers moving from SAN Volume Controller or Storwize versions earlier than 7.1 to 7.1 and higher the SPC-2 bit should not be changed on a production system and should remain "Disabled". Note that VMAX3 with 5977 the SPC-2 Bit is set to Enabled and is none configurable. VMAX 3 is supported on SVC and Storwize 7.3 and higher only For customers running 7.1 and higher and installing a new VMAX the SPC-2 bit can remain at the default setting of "Enabled". Changing the setting of the SPC-2 bit on a production system is not supported and may cause issues. | |
| SCSI_Support1(OS2007) | Enabled | Enabled | 1. This director bit can be modified to comply with the required setting or desired setting if it is optional either on the target port basis or initiator basis | |
| WP_Bypass(WPBP) | Disabled | Disabled | ||
| Director Bit Fibre Specific Flags | VMAX 10K 20k 40k | VMAX 100K 200K 400K | Notes | |
| Volume_Set_Addressing(V) | Disabled | Disabled | ||
| Non_Participating(NP) | Disabled | Disabled | ||
| Init_Point_to_Point(PP) | Enabled | Enabled | ||
| Access_Logix(ACLX) | Enabled | Enabled | ||
| OpenVMS(OVMS) | Disabled | Disabled | ||
| AS400(AS4) | Disabled | Disabled | ||
| Auto_Negotiate(EAN) | Enabled | Enabled | ||
| VNX_Gateway_Direct_Attach | Disabled | Disabled | ||
| Show_ACLX_Device | N/A | Disabled | Do not enable this bit for SVC attachment | |
