correct, do not use "unmap" option whenever shared PG involved.
Hello,  There are two masking Views named as MV1 and MV2.       --> MV1 contains SG1, IG1 and PG MV1 and MV2 have two separate storage group named as SG1(in MV1) and SG2(in MV2).      --> SG1 contains dev1, dev2, dev3 These masking views have different initiator groups IG1(in MV1) and IG2 (in MV2).       --> IG1 contains h1, h2, h3 same port group (PG) is added to both the masking views (MV1 & MV2)  Storage groups SG1 and SG2 have few devices(dev1, dev2, dev3) in common. So, dev1, dev2, dev3 are in both the storage groups SG1 & SG2.  What I need to acheive:      --> I need to unmask dev1, dev2, dev3 from h1, h2, h3      --> I dont want disruption or affect to the host access in MV2 in any case. Since these are common devices.      --> If I delete MV1 then would it affect MV2 host and LUN access in case manner ???      --> Should I just remove dev1, dev2, dev3 from SG1 and then delete the SG1 ????
