Adding more than 256 devices in storage group for NS80
what is the maximum number of devices that can be part of a storage groups on CX4-960? We have this CX connected to NS80 and we already have 220 devices in the storage group for the NS. While adding more LUNs it is warning that "HLU Numbers higherthan 255 may result in application outages if not supported by the host failover software"
We are running a CX4-960 and intially we had 2 Tray of 146GBs and created two LUNs of size 267GB from R5 (4+1) RG and when we got 300GB drives we started binding 4 LUNs of 267GB to match the same LUN size of 146GB Drives RG and added to same Celerra pool. As the celerra pool is running out of space we need to add more LUNs of size 267GB to it from 300GB drives and would like to know HLU numbers higher than 255 is supported on Celerra and what is the maximum number of devices that can be part of a storage group in CX4
thanks in advance.

easy enough to test, assign a LUN to the storage group and set its Host ID to something like 300. Rescan Celerra and see if it shows up.

are you exceeding any other limitations on Celerra ? Like file system number or total storage per datamover. While flare 29 supports more LUNs per storage group i could not find anything that states if Celerra will support anything more than 256 LUNs per target.
With R28, the max is 256, across all of the CX4-series arrays.
With R29 :
CX4-120 - 512
CX4-240 - 512
CX4-480 - 1024
CX4-960 - 1024
Total storage for a Data
Mover (Fibre Channel
Only)
Celerra Version 6.0
16 TB = NX4
32 TB =NS20, NS-120
64 TB =NS40, NS-480,
NS40G, NS-G2
128 TB = NS80,
NS80G, NSX
256 TB = NS960,
NS-G8
Celerra Version 5.6
8 TB = CNS (514 DM)
10 TB = NX350,
NS500
16 TB = NX4, NS700
32 TB = NS20, NS120
64 TB = NS40, NS480,
NS40G, NS-G2,
VG2
128 TB = NS80, NS960,
NS80G, NSX,
NS-G8

Thanks Dynamo. We are on Flare 29 and Dart 5.6.51.320. With flare 29 supporting 1024 devices per SG we are good there. But celerra will support it? File system numbers are less and the total capacity is 120TB spread across 3 active DMs and we are good there for per DM capacity.
