Hi Tuncel, Here are a few options for you:
- Use in-guest backups in conjunction with the VMSKIPMAXVMDKS - Use FCM for VMware exclusively for these large VMDKs - Allocate 2 TB disks (or less) As for helping us gauge interest in this... Instead of creating a new RFE, there are a few of them out there that you can go out and vote for to increase the priority. https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=45460 Del ---------------------------------------------------- "ADSM: Dist Stor Manager" <ADSM-L@VM.MARIST.EDU> wrote on 11/13/2014 11:25:36 AM: > From: Tuncel Mutlu (BT İşletim ve Teknik Destek Bölümü) > <tuncel.mu...@akbank.com> > To: ADSM-L@VM.MARIST.EDU > Date: 11/13/2014 11:30 AM > Subject: Re: VMWARE VMDK size limit > Sent by: "ADSM: Dist Stor Manager" <ADSM-L@VM.MARIST.EDU> > > After comminicating with local and remote IBM teams, that's what I learnt: > - TSMVE doesn't support VMDK disks larger than 2 TB (and therefore > cannot backup them), although VMWARE VMDK file size limit is now 64 > TB (and we already have some larger than 2 TB VMDK files).
